Abstract

In this paper, a dielectric-loaded broadband antenna with frequency-insensitive E-plane radiation pattern has been designed. The optimized antenna with a dielectric has more constant and higher gain than the antenna without a dielectric and also has low return loss over wideband. Consequently, it is found that loading a dielectric and designing antenna shape is effective to improve E-plane radiation pattern and return loss simultaneously.

具有频率不敏感e平面辐射方向图的介质负载宽带天线
本文设计了一种具有频率不敏感e平面辐射方向图的介质负载宽带天线。优化后的带介质天线比无介质天线具有更高的恒定增益和更低的宽带回波损耗。结果表明,加载介质和设计天线形状可以有效地同时改善e面辐射方向图和回波损耗。
