| 摘 要： | 本文介绍了微带天线的小型化的发展和圆极化天线的特性。在微带天线腔模理论的基础上，通过附加缝隙微扰单元实现单馈点的单层贴片的圆极化天线，并在此基础上，采用在天线表面开槽嵌缝的手段，设计出一款小型化的圆极化天线。通过仿真实验，对比两种天线的结果，可以看出本文设计的两款天线均能满足圆极化性能的要求，而经过嵌缝的天线实现了天线小型化的目的。

| Abstract: | This paper describes the characteristics of the miniaturization of the microstrip antenna and circular polarized antenna.On the cavity model theory of microstrip antenna, The single-layer circularly polarized patch antenna with single feed point canproduced by the additional gap perturbation unit, and designed a small-size circularly polarized antenna by slotted antennasurface .Compared results of the two antennas by simulation, we can see they all conform with the requirements of the circularpolarization, but, the slotted antenna achieves to the purpose of Compact Antenna |
