An Improved Slotted Patch Antenna for RFID Application
In this paper, the authors proposed a Radio Frequency IDentification (RFID) Reader Antenna which operates on ISM band with frequency range from 902 to 928 MHz and bandwidth of the antenna is 58MHz. Antenna consist of rectangular patches on Rogers RO4360 substrate with microstrip feed line. Return loss of the antenna comes out to be about -39.98 dB on behalf of the frequency 907MHz. Gain of the proposed antenna is 5.21dB. This antenna is simulated on CST Microwave Studio and the results are thoroughly discussed in the paper.
