Radio Frequency IDentification (RFID), The operated in 2.4 GHz RFID systems is energy and data transmission using propagating radio signal (E-field transmission). This is exactly the same principle as that used in long-range radio communication systems. The reader's antenna generates a propagating radio wave use far-field communication, which is received by the antenna in the tag. In this paper the microstrip antennas used both for reader antenna and tag antenna and simple patch antenna of this type radiates a linearly polarized wave. The authors investigated and analyzed to the vertical and horizontal polarization arranges in RFID communications link.
