Abstract :
A simple design for a wideband circularly polarised planar monopole antenna array is presented. The attractive characteristics of the proposed antenna array are the wide impedance bandwidth of 87.3% (1 to 2.55%GHz), the 3%dB axial ratio (AR) bandwidth of 95% (1.05 to 2.95%GHz), and the maximum gain within the 3%dB AR bandwidth of about 4%dBi.
