Summary:
This paper presents a high gain, circulary polarized, wideband rectangular microstrip patch Radio Frequency Identification (RFID) reader antenna at UHF band. In order to obtain the circulary polarization and wide band characteristics, edge of the patch antenna is truncated and slots are insearted. To match the impedance of the antenna to the transmission line, the feeding position is also optimized.
