摘要

提出了两种工作在GPS Li波段的圆极化开环天线，以方形贴片AMC地平面为支撑。前者由共面波导(CPW)馈电，后者由垂直探头馈电。CPW天线的S11和AR测量带宽分别为11%和6%，而垂直探针馈电天线的S11和AR测量带宽分别为21%和5%。两根天线都在期望的频率上提供了有用的孔视增益。

Circularly polarized open loop antenna backed by square AMC with different feeding mechanisms

Two circularly polarized open loop antennas, backed by square patch AMC ground planes and operating at the GPS Li band are presented. The first one is fed by a co-planar waveguide (CPW) and the second one is fed by a vertical probe. The CPW antenna has provided measured S11 and AR bandwidths of ~11% and 6% respectively compared to ~21% and 5% for the vertical probe fed antenna. Both antennas have provided useful bore-sight gain at the desired frequency.
