Basic Characteristics of Radio Frequency Propagation Attenuation What cannot be avoided in RF propagation is attenuation. Literally, attenuation is to reduce the strength of the RF signal. To be precise: when the signal propagates in the transmission medium, a part of the energy will be converted into heat energy or absorbed by the transmission medium, resulting in the continuous weakening of the signal strength. This phenomenon is called attenuation. The phenomenon that the signal of the UHF RFID reader decreases in amplitude after passing through the water medium is attenuation. The general attenuation is represented by L (Loss): Among them, Po represents the power before attenuation; Pi represents the power after attenuation. L is negative in dB under attenuation and Po is less than Pi Attenuation in RF propagation exists in the following places: In the cable—The resistance between the cable and the connector converts RF into heat. The energy expansion caused by the path in the air is the biggest factor of failure, and dust, rain and fog in the air will cause failure. Passive components in the system heat up, causing the RF signal to fail. Artificially added to the system to reduce the sincerity (useful). It should be emphasized that attenuation wells are not necessarily a bad thing. In many cases, attenuation is performed at the front end of the circuit in order to protect the circuit, or attenuation is performed before the antenna output in order to control the radiation range, all of which are positive for the entire system thing. Gain 1) RF gain Gain is the opposite of attenuation, resulting in increased RF signal strength. RF gain (not antenna gain) is generated by active devices. It can be understood that to amplify a signal, it must be given corresponding energy. Generally, gain is expressed as Gain: Among them, Po represents the output power, and Pi represents the input power. Gain's dB is negative for attenuation and Po is less than Pi: Gain's dB is positive for gain and Po is greater than Pi. If a positive gain is achieved, external energy needs to be introduced and supplied to the amplifying device to achieve signal amplification. Below Figure is a schematic diagram of attenuation and gain, where the signal is attenuated by passive devices to reduce amplitude and generate heat loss; the amplitude is enhanced by the energy gain provided by active devices. One thing to note is that the operating frequency of the signal remains the same regardless of gain or attenuation. 2) Antenna gain When it comes to antenna gain, it needs to be distinguished from RF gain, which is completely different from RF transmission gain. The gain of an antenna is to increase the intensity of energy in a particular direction rather than to increase its total energy. Antennas are generally passive components and cannot provide additional energy to enhance the RF signal. Below Figure is a schematic diagram of the radiation of a pot-shaped microwave antenna. The...

Three Minutes to Take You to Understand RFID Technology RFID technology actually refers to radio frequency technology. Its technology mainly relies on the principle of magnetic field or electromagnetic field to realize two-way communication between devices through radio frequency, so as to realize the function of exchanging data. The biggest feature of this technology is that it can obtain each other without contact. RFID information, ETC, logistics, and libraries are several typical application scenarios. The commonly used radio wave frequency bands for RFID technology mainly include: low frequency, high frequency, ultra-high frequency and microwave frequency bands.RFID system compositionRFID system is mainly composed of three parts: reader, electronic label and data management system. RFID Reader: Also known as a reader , it is mainly used to read out the information in the electronic tag, or write the information required by the tag into the tag. According to different uses, readers are divided into read-only readers and read/write readers, which are the information control and processing center of the RFID system. When the RFID system works, the reader transmits radio frequency energy in an area to form an electromagnetic field, and the size of the area depends on the transmission power. The tags in the coverage area of the reader are triggered, send the data stored in it, or modify the data stored in it according to the instructions of the reader and can communicate with the computer network through the interface . RFID Tag: The electronic tag is mainly used to store certain data information. At the same time, it will accept the signal from the reader and send the required data back to the reader. The electronic tag is generally attached or fixed to the on the item. Data management system: The main work is to process the electronic tag data transmitted by the reader for analysis, and at the same time complete the functions required by the user. For example, the following system flow: How RFID systems work When the rfid tag is within the recognition range of the reader, the reader emits radio wave energy of a specific frequency, and the electronic tag will receive the radio frequency signal sent by the reader and generate an induced current. Using the energy generated by this current, the electronic tag sends out the information stored in its chip. Such electronic tags are generally referred to as passive tags or passive tags, or the tags actively send a signal of a certain frequency to the reader, and such electronic tags are generally referred to as active tags or active tags. After the reader receives the information returned by the electronic tag, it decodes it, and then sends it to the relevant application software or data management system for data processing. RFID classification RFID technology can be divided into three categories according to the power supply method of its tags, namely passive RFID, active RFID and semi-active RFID. 1...

How To Select an RFID Antenna An RFID antenna is a necessary part of any RFID system. Unless the antenna is embedded into a reader, you will have to select and purchase the right antenna for your application. And there are a lot of options to select from. Frequency– this will depend on your tags – choose between LF, HF, UHF or Microwave frequency. Frequency Region– this will depend on country of operation and will affect only the UHF frequency. As you know, due to regulations, the frequency bands for UHF RFID slightly differ for US, Europe and other regions. Most UHF antennas are specified as globaland they are tuned for operation between 860 to 960 MHz. You can also find antennas that are specifically tuned for each region, which slightly improves their performance in the particular region. For instance, 865 - 868 MHz antenna will perform better when deployed in Europe than a global antenna, although this may not be distinguishable in most applications. Global antenna will work well for most applications; however, you can choose region-specific antenna for difficult deployments (long read ranges, RF challenging environment) or where global is not available. Read range and size– smaller antennas within the same frequency will have shorter read range and vice versa. The antennas with the shortest read range for UHF technology will be Near Field Antenna, that utilize near field as opposed to far field as regular UHF antennas. These are often used for item tracking and where short ranges are required for item singulation and/or security purposes. Profile width– if you are short on space or for esthetic reasons, you may need to look for low profile antennas that have a side connector or a side pigtail. Gain– gain affects read range and beamwidth. Antennas with higher gain will have longer read range but narrower beam. Antennas with lower gain will have shorter read range and wider beam width. Select antenna gain based on the shape of your interrogation zone and coverage needs. Most common gain is 6dBi but you can find antenna with 1 dBi (low gain) and also with 11 dBi (high gain). Polarization– you can select between circular and linear polarization. Circularly polarized antennas will have shorter read range but will be less orientation sensitive. You can select between right hand circularly polarized antennas (RHCP) or left hand circularly polarized antenna (LHCP). Sometimes you can see dual circularly polarized antennas that have both left hand and right hand polarization. Linearly polarized antennas will provide longer read range and more focused beam but will read only tags that have antennas parallel to the plane of wave. If your tag orientation is not fixed, especially when using single dipole tag antennas (which are most common), you should select a circularly polarized antenna. VSWR– voltage standing wave ratio or also called return loss - Due to mismatches in impedance within the connector, some of the signal is reflected. The ratio of the i...

Dual-frequency RFID is a relatively special application market. It is still relatively narrow and the industry chain is relatively simple. At present, the dual-frequency RFID chips on the market mainly use UHF+HF to make the same IC. There are still some scenarios in the market that use UHF. Tag + HF tag two different tags combined scheme. In addition to the chip threshold, dual-frequency tag equipment and manufacturing are also more difficult than ordinary tags, because the working principles of HF and UHF two different frequency bands are completely different, one is near-field coupling and the other is far-field radiation, which requires two different antenna combinations. In addition, the current usage of dual-frequency products is not large, so dual-frequency RFID products are more expensive than ordinary ones, whether they are chips or tags. According to the information we have investigated, the application volume and application scenarios of dual-frequency RFID tags are rapidly increasing, and may become a new market growth point. 1. Introduction to the advantages of dual-frequency RFID The advantages of dual-frequency RFID products are mainly in the following two aspects: >>Advantage 1: The function of UHF RFID for rapid inventory in large quantities is retained The biggest advantage of UHF RFID is that it has a long transmission distance and can be read in groups. It is very suitable for some scenarios that require quick inventory, especially in the B-side warehousing logistics and sorting links. >>Advantage 2: retains the ability of HF RFID to interact with mobile phones Because the NFC on the mobile phone is a kind of HF RFID technology, the HF RFID tag can interact directly with the mobile phone, which greatly expands the use boundary of RFID. Anti-counterfeiting traceability requirements. Therefore, dual-frequency RFID tag products can not only meet the needs of the B-side for efficient turnover, anti-lost, and visual management, but also meet the needs of the C-side crowd for anti-counterfeiting and traceability, which can form a good closed loop in business. 2. Dual frequency RFID market and application introduction The application scenarios of dual-frequency RFID products mainly have the following characteristics: The usage scenarios need to combine the high inventory efficiency of ultra-high frequency and the characteristics of high frequency interaction with mobile phones, which requires a relatively large amount of applications and concentrated, and then there is a demand for large-scale inventory; in addition, the consumption attributes of products are strong , need to interact directly with consumers. The unit price of the product in the application scenario is more expensive, because the product is more expensive, it will stimulate the consumer's need for anti-counterfeiting traceability. Only high-value scenarios can afford such a cost input. There is a strong demand for authenticity identification, but there is...

What is RFID Air Interface Communication Protocol? The air interface communication protocol is the specification of the information exchange between the reader and the tag, and the purpose is to solve the interconnection problem between the equipment of different manufacturers. ISO/IEC has formulated air interface protocols for 5 frequency bands. This idea fully reflects the relativity of standard unification. A standard is aimed at the common needs of a wide range of application systems and can meet a wider range of application needs. ISO/IEC 18000-1 Information Technology: (Radio Frequency Identification Based on Item Management)Reference Structure and Standardized Parameter Definition . It regulates the communication parameter table of the reader and the tag, the basic rules of intellectual property rights, etc., which are commonly observed in the air interface communication protocol. In this way, the standards corresponding to each frequency band do not need to repeatedly specify the same content. ISO/IEC 18000-2 Information Technology: (Radio Frequency Identification Based on Item Management) applicable to low frequency 125~134kHz, specifies the physical interface for communication between the tag and the reader, the reader should have Type A (FDX) and ability to communicate with Type B (HDX) tags; specifies protocols and commands plus anti-collision methods for multi-tag communication. ISO/IEC 18000-3 Information Technology: (Radio Frequency Identification Based on Item Management) applicable to high frequency 13.56MHz, and specifies the physical interface, protocol and command between the reader and the tag plus anti-collision methods. Anti-collision protocol can be divided into two modes, among which, mode 1 is divided into basic type and two extended protocols (multi-response protocol without time slot and non-termination and time-slot termination adaptive polling multi-transponder reading protocol): Mode 2 adopts the time-frequency multiplexing FTDMA protocol, and a total of 8 channels are suitable for the situation with a large number of tags. ISO/IEC 18000-4 Information Technology: (Radio Frequency Identification Based on Item Management) suitable for microwave band (although 2.4GHz is in the UHF frequency band, it is conventionally called the microwave band, for the same reason, 5.8GHz RFID should be in the SHF band, which is also counted in the microwave band) 2.45GHz, which specifies the physical interface, protocol and command between the reader and the tag, plus anti-collision methods. The standard includes two modes: Mode 1 is the working mode of passive tags, and the reader will talk first; Mode 2 is active tags, and the working mode is that the tag will talk first. ISO/IEC 18000-6 Information Technology: (Radio Frequency Identification Based on Item Management) is applicable to the ultra-high frequency band 840~960MHz, and specifies the physical interface, protocol and command between the reader and the tag plus anti-collision...
