Abstract

This paper presents a novel design of a circular polarized antenna for ultra-wideband (UWB) applications. A simple narrowband patch antenna is optimized to the geometry of the UWB antenna. A partial ground plane, a couple of cross slots, and additional slots were designed and optimized using CST Microwave Studio. Results indicate that the proposed antenna exhibits good circularly polarized radiations. The 3 dB axial ratio bandwidth is higher than 87.8%. Simulation results and measured values indicate that the antenna has an impedance bandwidth of 158.8% (1.4–12.2). In addition, the antenna exhibits good radiation characteristics and obtains a reasonable gain across the band, which makes the antenna an excellent candidate for UWB applications.
