本文提出了一种H缝隙耦合馈电的超宽带小型化圆极化天线。该超宽带天线具有频带较宽、体积较小、圆极化性能较好等特点，应用范围很广。本次设计的天线工作频率范围是2.2 GHz~2.4 GHz，驻波相对带宽达28.9%，频带内最大增益值为5.74 dB。该天线可以单独使用，也可用作相控阵天线的单元天线使用，适用于导航和卫星通信领域。
An UWB compact circular polarized antenna is presented in this paper. The H slot is used as aper-ture to couple energy to patch antenna. This antenna has some advantages as wideband, small volum and performance in circularly polarizing, so it has broad appliance prosperity. This antenna operates from 2.2 GHz to 2.4 GHz, the relative bandwidth is 28.9% and the maximum gain is 5.74 dB. This antenna can be used not only a single antenna but element antenna in the array antenna. It can be used in navigation and satellite communication.
