Abstract

A circularly polarized (CP) antenna with enhanced axial-ratio and half-power beamwidths using non-uniformly compressed high-order mode dipoles is proposed in this paper. First, wide half-power beamwidth (HPBW) at E-plane is obtained by a third-mode dipole with proper non-uniform compressed parameters. Then, a crossed non-uniformly compressed high-order mode dipole is proposed, and wide axial-ratio beamwidths (ARBW) and HPBWs are both achieved in two orthogonal planes. Next, a ✳-shaped CP antenna based on non-uniformly compressed high-order mode dipoles is presented with wide beamwidths in all cut-planes in the upper hemisphere. Finally, the antenna is fabricated and measured to verify the design. The measured results show that the HPBWs are larger than 109° and ARBWs are larger than 118° in eight cut-planes.
