High-Gain Annular Ring with Meander Slots Antenna Array for RFID Applications

In this paper, a high-gain annular ring with meander slots antenna array is presented. The proposed design is realized on two different substrate materials separated by a foam layer of 7.5 mm to enhance the operating bandwidth. The antenna is designed to operated as UHF-RFID reading antenna over center frequency of 915 MHz with operating bandwidth of 49.25 MHz (around 5.38%). The overall antenna optimized dimensions are 240×240×11.56 mm3. An overall total realized gain of 12.5 dBi is achieved at the intended center frequency. The proposed antenna exhibits stable radiation capabilities over the operating band. Good agreement is obtained between both CSTMWS, and HFSS simulators.
