Abstract :
An ultra-wideband circularly-polarized (CP) microstrip antenna is presented with the introduction of one wideband 90deg feed network. The CP patch antenna experimentally offers a 10-dB impedance bandwidth of 71.7%, 3-dB axial-ratio bandwidth of 81.6% and a gain bandwidth of 52.2% with its highest gain of 8.1 dBi at 1.8 GHz.
