摘要

提出了一种基于双极化磁电偶极子天线的宽带圆极化天线。在连接宽带90°移相器和威尔金森功率分配器后，所提出的双极化天线实现圆极化(CP)辐射。该CP天线在1.23 ~ 3.23 GHz范围内具有89.7%的宽阻抗带宽，其中SWR≤2，覆盖了1.28 ~ 3.05 GHz范围内的整个3db轴比(AR)带宽82%。在此工作频带中，本天线在1.45 GHz以上具有大于5 dBi的宽边增益。考虑到受阻抗、AR和增益限制的共同重叠带宽，该天线的有效带宽为71%。

A wideband dual-fed circularly polarized antenna

A wideband circularly polarized antenna based on dual-polarized magneto-electric dipole antenna is proposed. After connected to a broadband 90° phase shifter and a Wilkinson power divider, the proposed dual-polarized antenna achieves circularly polarized (CP) radiation. This CP antenna exhibits a wide impedance bandwidth of 89.7% from 1.23 - 3.23 GHz with SWR ≤ 2 which covers the whole 3-dB axial-ratio (AR) bandwidth of 82% from 1.28 - 3.05 GHz. In this operation frequency band, the proposed antenna has a broadside gain of larger than 5 dBi above 1.45 GHz. Considering the common overlapped bandwidth limited by the impedance, AR and gain, the proposed antenna exhibits an effective bandwidth of 71%.
