In this paper, a microwave frequency band 2x2 microstrip phased antenna array is designed for an RFID (Radio Frequency IDentification) reader system. The main focus will be on optimizing of dimensions of patch antenna for RFID application with resonance frequency of 2.45GHz. In this paper, they discuss the microstrip patch antenna, feeding techniques and phased array antenna with their advantage and disadvantages over conventional microwave antennas. The phased antenna array is used as the receiving antenna in a commercial reader system; experimental results indicate that the coverage of the RFID system with the phased array antenna is superior to with a conventional broader beam width microstrip patch antenna.
