Radio frequency identification (RFID) technology is a kind of automatic identification technology for non-contact data communication in wireless channels. It is derived from radar technology and is widely used in the Internet of Things. With the rapid development of RFID technology, RFID applications have been widely used in RFID systems such as warehouse logistics, production line management, supply chain management, access control and vehicle management, livestock farming, asset management, item tracing, and food security. In view of the research and practical application of the key technologies of the Internet of Things in recent years, they have shown a good development trend, which has also led to the rapid development of RFID technology. Dawn produces some RFID antennas with frequency of 865 MHz-868 MHz or 902 MHz-928 Mhz. Most RFID antennas type can be customized by your choice. Including different polarization: horizontal, vertical and circular.
Which kind of antenna is used in RFID tag?
Linear antennas commonly propagate a slender however longer tag examine field. Circular antennas propagate a a whole lot wider however shorter tag examine field. Circular antennas are extra many times used for most purposes whereas linear antennas are used to study tags in unique centered areas
The special sorts of RFID Systems
RFID structures are damaged down through the frequency band inside which they operate, frequency refers to the dimension of the radio waves used to talk between the device components. RFID structures function in low frequency (LF), excessive frequency (HF) and ultra-high frequency (UHF) bands. Radio waves behave pretty exclusive at every of the cited frequencies with benefits and risks related with the usage of every frequency band.
A decrease frequency, outcomes in a shorter study vary and a slower facts examine rate, however multiplied skills for analyzing close to or on steel or liquid surfaces. Systems running at greater frequencies commonly have quicker statistics switch quotes and longer examine tiers than decrease frequency systems, however are extra sensitivity to radio wave interference induced by means of drinks and metals in the environment.
What is the range of rfid antenna types?
In general, low-frequency and high-frequency tags tags are examine from inside three toes (1 meter) and UHF tags are study from 10 to 20 feet. Readers with phased array antennas can extend the read range of passive tags to 60 toes or more.
RFID antennas are every so often exterior to the RFID reader and different instances the RFID antenna is integrated into the RFID reader as a single piece solution. Additionally, each low frequency (LF) and ultra-high frequency (UHF) RFID antennas differ in dimension, from smaller than a pencil eraser to as giant as a meter square. UHF and LF RFID antennas are unique to sure frequencies and are very a whole lot focal in nature, which means there is a unique region from which the RF sign is emanated, and the RFID antenna and RFID tag want to be orientation particular to every other.

How do rfid antenna types work?
Unlike RFID readers,&;RFID antennas are dumb units that acquire their energy at once from the reader. When the reader's electricity is transmitted to the antenna, the antenna generates an RF subject and, subsequently, an RF sign is transmitted to the tags in the vicinity.
There are three one of a kind sorts of RFID antennas: Linear Polarization (dipole antennas) - the electromagnetic wave propagates completely in one aircraft (Vertical or Horizontal) in the course of the sign propagation. This is the fine wave propagation when the tag orientation is regarded and fixed.
