摘　　要：通过理论分析和HFSS三维电磁结构软件仿真，设计出一种圆形弹载圆极化微带天线。该天线在±60°的天线方向扫瞄空间内．天线极化轴比为1．06～3．3dB。增益为4．7dBi。文中给出了圆形圆极化天线的具体设计尺寸和仿真天线方向图、极化轴比图和驻波图。The design of a missile-borne circularly polarized circular microstrip antenna was proposed. Theoretical analysis and simulation results with HFSS show that the antenna can achieve a maximal gain of 4. 7dBi and polarization axial ratio of 1.1 -3.3dB in the direction of ±60° scanning space. The results of the simulated and the antenna size were presented.
