摘要：
In this work, dielectric resonator antenna with superstrate is designed and analysed. Here, Frequency selective surface incorporated as superstrate on DRA behaves as a polarizer to achieve circular polarization. Impedance bandwidth of the DRA is 73.67% at 5.81 GHz operates in the frequency band 3.68–7.96 GHz. 3 dB axial ratio bandwidth is 18.93% at centre frequency 5.81 GHz and the overlapping bandwidth is 25.7%. Peak Gain of the antenna is also enhanced by 5.6 dBic at 6.5 GHz. The design structure simulated on Ansoft HFSS 15 and experimentally verified.
