摘要

介绍了一种新型的单端间隙耦合短贴片天线。研究了有限地平面对传统短贴片天线和新型间隙耦合天线辐射方向图的影响。结果表明，间隙耦合的SPA具有较好的辐射性能，具有稳定的对称辐射模式和较好的交叉极化抑制能力。此外，与用于空气基板的传统SPA相比，间隙耦合SPA在减小电尺寸的同时显示出更高的增益。

Shorted Patch Antenna with Symmetrical Radiation Patterns and Enhanced Gain

A novel single-ended gap-coupled shorted patch antenna (SPA) is described in this paper. The finite ground plane effect on radiation patterns of both the conventional shorted patch antenna and the novel gap-coupled SPA is investigated. It was found that the gap-coupled SPA achieves better radiation performance with stable symmetrical radiation patterns and better cross polarization suppression. Moreover, the gap-coupled SPA shows enhanced gain with reduced electrical size compared to the conventional SPA for the air substrate.
