Dual band microstrip patch antenna for RFID application of 900MHz and 2.45GHz

900MHz, 2.45GHz RFID 이중 대역 마이크로스트립 패치 안테나

In this paper, a dual band microstrip patch Antenna is designed for RFID Application. The antenna shows a good performance at the frequencies, 900MHz and 2.45GHz for the radiation characteristics and input impedance matching, as well. The reflection factor is lower than -25dB and a good directivity higher than 5dB is achieved for both frequency.
