新型测地线双锥天线的研究

一种新型测地线双锥天线的研究

内容简介：介绍了一种新型测地线双锥天线，该天线能够实现全方位面上的波束扫描，具有广阔的应用空间。采用几何光学法结合测地线理论分析了其工作原理，重点阐述了圆柱面上射线传输路径的问题，并对该天线在单端口和双端口激励情况下的方向图分别进行了分析和计算。在以上基础上，设计加工完成了一款工作在6～8 G Hz的新型测地线双锥天线，给出了其具体结构和尺寸。理论结果与实测结果具有较好的一致性，表明了几何光学法在测地线双锥天线分析和设计中的适用性。

Abstract：In this article ,a novel geodesic biconical antenna that can point a beam to any direction of azimuth is proposed ,w hich has a bright application future .Combining geometric optics and geodesic theory ,based on the analysis of the antenna ,this thesis mainly focuses on the problem of the radial transmission route on the surface of column and respectively calcu-lates the radiation pattern of the antenna on the one port and two ports feeded in .On the ba-sis of the research ,this thesis devises a noval geodesic biconical antenna working between 6-8 G Hz.Furthermore ,concrete structure and size of the antenna have been put out .Academic results are appropriately coincident with experimental results in the thesis ,which manifests the application of geometric optics in the analysis and design of the antenna .
