HUAYUAN RAIN RFID UHF Reader Antenna transmits a wave that has both electrical and magnetic properties and is known as an electromagnetic wave. There are 2 different types of RFID antennas, Circular Polarization or Linear Polarization:

Linear Polarization (dipole antennas) – the electromagnetic wave propagates entirely in one plane (Vertical or Horizontal) in the direction of the signal propagation. This is the best wave propagation when the tag orientation is known and fixed. The RFID antenna and RFID tag should be matched in polarization to obtain the best read rates.

Circular Polarization (helix, crossed dipoles and patch ) – the electromagnetic wave propagates in two planes creating a circular effect (like a corkscrew) making one complete revolution in a single wavelength time frame. Since the RFID antenna continuously emits a wavelength the rotational field will eventually cover any tag that is in its path. This is best to use when tag orientation is unknown, but you lose at least 3dB when compared to a linear polarized antenna. Circular polarization can be right or left handed hence the RHCP and LHCP options for circular polarized antenna.

HUAYUAN RAIN UHF RFID Reader Antenna is designed high-end UHF RFID Antenna, high gain but low standing-wave ratio brings best performance. Engineering plastic housing, IP66 rugged construction, high protection level for wide using with our S-8600, S-8800 RAIN UHF fixed reader, such as assets tracking, warehouse management, intelligent traffic management, vehicle tracking, production line management, intelligent weight measurement etc.
