摘要
介绍了一种L频段双通道非接触式旋转关节的原理。该旋转关节采用新颖的外通道结构方式和多点馈电技术,解决了外通道的旋转抖动问题。测试结果表明,该旋转关节不仅损耗低、驻波比小,而且使用寿命长、可靠性高。
This paper introduces the principle of an L- band dual channel rotary joint. The rotary joint has new configuration in outchannel and uses the technogy of four feeds to slove the thrill in outchannel when rotating. The rotary joint is featured by low insert loss,low VSWR,long life and high reliability.
