多波段共面天线的研究

The Study on Multi-band Coplanar Antenna

跟踪测量雷达因其精度要求,波束宽度很窄。为实现雷达自引导功能,本文介绍了一种跟踪测量雷达的多频段共面的天线技术,重点对共面天线设计、组合馈源设计以及双频段自引导概率计算进行了论述,并给出了一些设计实例和仿真计算结果。结果表明:多频段天线的应用完全可用一部雷达取代两部或两部以上的雷达。

Because of the accuracy requirements of tracking radar, the beam width is very narrow. To implement the self-guidance of radar, the technology of multi-band coplanar antenna for tracking radar is described, The design of coplanar antenna, the design of composite feed and the self guiding probability calculation of dual-band radar are discussed specially. Some design examples and simulated results are given. The obtained results show that the application of multi-band coplanar antenna make it possible to use one radar to replace two or more radars.
