摘　　要：阿基米德螺旋天线是一种超宽频带天线,广泛应用于通信导航等领域。采用正弦函数加载方式对传统阿基米德螺旋天线进行了小型化设计。仿真结果表明,天线口面面积减小了30%,天线仍具有较好的驻波、增益等特性。The Archimedean spiral antenna, as a kind of ultra wideband antenna, is widely used in the communication and navigation and other fields. The miniaturization design of the conventional Archimedes spiral antenna is performed with sine function. The simulation results show that although the antenna aperture area is decreased by 30% , the antenna still has good VSWR and gain charac-teristics.
