Circularly Polarized Antennas

(3 products available)

 Circularly-polarized antenna rotates in a corkscrew pattern making one complete revolution during each wavelength. Circular polarized RFID antennas are suitable for where a wide variety of RFID tags on different surfaces need to be read in a smaller amount of space.Antennas have right and left circular polarization. These left and right circular polarization antenna release electromagnetic waves in spiral motion.  The electric field vector rotates counter clockwise as far as it gets from the antenna that’s called the left Hand Circular Polarization(LHCP). When its rotates clockwise call it Right Hand Circular Polarization(RHCP).  Circular polarized antennas send and receive all planes Radio signals which are reflected or absorbed depending on the material they come in contact with,the signal strength is not lost, but is transferred to a different plane and are still utilized.
