高频段天线罩的建模与计算分析

摘要

Radome is based on the antenna need in disguise .Designing an ideal radome to maintain the antenna under the condition of the maximum gain of antenna for effective protection and electromagnetic camouflage ,even some performance improvements of antenna has the extremely vital significance .This paper introduces the process of the development of a L ~S band radome is introduced ,3D graphics software Solid Works is used to design the spherical radome's structure ,then soft-ware FEKO graphics is used to analyze the electromagnetic characteristics of antenna radome ,the loss and the wavelet coeffi-cients of the electromagnetic wave in the half wave through a typieal medium interlining are measured .%天线罩是基于天线伪装的需要[10]。设计理想的天线罩，对维持天线在最大增益条件下对天线进行有效的保护和电磁伪装，甚至对天线的某些性能进行改善具有极其重要的意义[1]。论文介绍了某 L ～ S 波段天线罩的研制过程，利用三维制图软件 Solid Works 对球状天线罩的结构进行三维设计，再将图形导入天线分析软件 FEKO 对天线罩进行电磁特性分析，测定该波段内的电磁波在穿过某种典型媒质半波长夹层时插入损耗和透波系数[4]。
