Abstract
A broadband circularly polarized (CP) antenna with both a wide half-power beamwidth (HPBW) and a wide axial ratio beamwidth (ARBW) is proposed. The proposed antenna is composed of a pair of crossed dipoles and a U-shaped metal reflecting cavity. The fan-shaped patches of the dipoles can effectively increase the operating bandwidth of cross dipoles, and the U-shaped metal reflecting cavity can further increase the impedance bandwidth (IBW) and axial ratio (AR) bandwidth of the antenna while enhancing HPBW and ARBW. To validate the feasibility of the design, the proposed antenna is fabricated and measured. The measured results show that the bandwidths of the antenna are 89.2% for -10 dB impedance and 82.7% for 3 dB AR. In addition, both HPBW and ARBW greater than 120˚ are achieved within a relative bandwidth of 63.1%.
