X波段宽频带波导-同轴铰链的研制

波导-同轴旋转铰链是由矩形波导-同轴波导构成，是雷达系统中的关键元件。本文首先简要介绍了该铰链的基本工作原理，然后对铰链的旋转段、同轴-波导的耦合和激励进行了理论分析与设计，尤其是针对如何实现宽频带匹配问题作了较详细的实验研究。

Development of X-band,wideband waveguide-coaxial joint

The waveguide-coaxial rotary joint consists of the rectangular waveguide and the coaxial waveguide,is one of the key components in the radar system. In this paper, the basic operation principle of the joint is briefly introduced.The theoretical analysis and design of the rotating part of the joint and the coupling and exciting from the coaxial waveguide to the rectangular waveguide are presented.Especially the detailed experimental study on wideband match of the joint is demonstrated .
