针对星载无缆化通信的需求，研究了展宽印制天线工作带宽的方法。设计了星载小型化宽带全向印制天线，通过三维全波电磁仿真软件(CST)进行了仿真分析与优化设计。在此基础上加工了天线实物样件，并对其电性能进行了测试。仿真结果表明该天线具有小型化、宽带、全向等特点。

The method to achieve broadband printed antenna for satellite communications without cable is discussed. A broadband compact omnidirectional printed antenna is designed，and it is simulated and optimized by the Computer Simulation Technology(CST) software. A prototype is fabricated and tested.The measured results show that the proposed printed antenna is of the characteristic of wide bandwidth,omnidirectional far-field pattern, and compact size.
