Abstract
SummaryA low‐profile circularly polarized (CP) antenna with high gain and broad bandwidth is aimed at 5‐GHz Wi‐Fi applications using a symmetrical E‐shaped patch. Initially, the radiating element is modeled as a symmetrical E‐shape. An array of 4 × 4 rectangular patches are arranged periodically to make up a reactive impedance surface (RIS) structure. Furthermore, the RIS structure is deployed in the middle of a symmetrical E‐shaped radiating patch and a perfect electric conductor (PEC) ground plane. As a result, the broadband CP is achieved with high gain. The above‐mentioned combinations have achieved a −10‐dB reflection coefficient bandwidth of 21.4% (4.92–6.1 GHz) and a 3‐dB axial ratio (AR) bandwidth of 15.5% (5.25–6.1 GHz), and the antenna has attained a gain of 7.45–7.53 dBic.
