摘　　要：多径效应是影响卫星导航接收机测量精度的一个主要误差源，可以采用改进天线结构的方法，提高抗多径性能。本文从天线抗多径理论入手，描述了一种多频抗多径天线的设计和实现。测试结果表明，该天线具有良好的抗多径效果。Multipath effect is a main error source, which may infect the measurement precision of satellite navigation receiver. The anti-multipath property is enhanced by a way of improving antenna structure. Based on the anti-multipath theories about antenna, the design and implementation of anti-multipath antenna with multi-frequency are described. The result indicates that the antenna has good performance on anti-multipath.
