Truncated Corners Microstrip Patch Antenna for UHF RFID Reader Applications
In this paper, truncated corners microstrip patch antenna for UHF (Ultra High Frequency) RFID (Radio Frequency IDentification) reader applications is proposed. It consists of square patch radiator with two truncated corners and two unequal square slots on its diagonal axis. The coaxial feed is used and the simulation is carried out in Ansoft HFSS. The 10dB return loss bandwidth and VSWR of proposed antenna is 17.1MHz and 1.1 respectively. The overall antenna size is 55x55x2mm3.
