Abstract :
A compact circularly polarised printed antenna is presented. The antenna consists of a synchronous subarray of shorted patches with the required feed network etched on a high dielectric constant substrate located below the ground-plane of the antenna. The 10 dB return loss and the 3dB axial ratio bandwidths are 8.5 and 11.3%, respectively. The overall size of the proposed antenna is 0.195 λ0×0.195 λ0×0.0523λ0
