摘　　要：平面等角螺旋天线是1种非频变天线，对其进行分析研究，设计了工作在I^5GHz双臂平面等角螺旋天线。设计了1种梯形结构的微带巴伦来实现对天线的平衡馈电，使天线在整个频带内基本符合技术指标。仿真结果显示平面等角螺旋天线具有良好的圆极化和宽频带特性。Plane equiangular is a kind of non-frequency transforming antenna. Such a kind of antenna operating between 1-5 GHz is designed and studied. A trapezoidal structure of microstrip balun is designed to realize balanced feed. The antenna feed can conform to the technical specifications in the whole band. The simulation results show that the plane equiangular spiral antenna has good performance of circular polarization and broadband.
