摘　　要：设计了一种以空气为基板的超高频(UHF)圆极化矩形微带天线。该天线通过在微带贴片四周与中心开槽,减小了天线尺寸,实现天线圆极化的性能。进一步研究了天线的参数对圆极化性能的影响,通过天线参数的优化,使天线达到了良好的圆极化性能。An ultra-high frequency circularly polarized（CP）rectangular microstrip antenna on air substrate was designed. The antenna inserted four same slots on the microstrip patch and a small slot on the center of the patch, which could reduce the size of the patch and achieve the circular polarization operation. The impact of antenna parameters on its circularly polarized performance is introduced. Through optimizing the antenna parameters, experimental results show that a good CP radiation performance can be gained.
