Abstract

In this paper, a fabry-perot resonator (FPR) antenna for 5 GHz Wi-Fi applications with high gain and high impedance bandwidth (IBW) is proposed. For improving the performance of circularly polarised antennas, a 6 × 6 reactive impedance surface (RIS) based meta surface and a dielectric superstrate are used. The cavity created between superstrate and ground plane of a patch antenna acts as an FPR, improves the gain. RIS is used to make the antenna’s IBW better. The proposed antenna has an IBW of 18.7% (5.19 GHz–6.26 GHz), a 3 dB axial ratio bandwidth (ARBW) of 4.7% (5.39 GHz–5.65 GHz), and a gain of 10.3 dB.
