Wideband hook-shaped circularly polarized antenna

Abstract

A circularly polarised (CP) wideband hook-shaped microstrip fed patch antenna is presented. The wideband CP property for the proposed antenna is achieved by the hook-shaped branch in the ground plane and inverted asymmetric arm L-shaped microstrip fed. With an optimised dimension of the proposed antenna parameter, the experimental results show that the antenna has a 10 dB impedance bandwidth of 1.41 GHz (1.84-3.25 GHz) and 3 dB axial ratio bandwidth of 1.67 GHz (1.86-3.53 GHz). © 2014 The Institution of Engineering and Technology.
