一种V波段波导-微带对极鳍线过渡结构的设计研究

Research and design of a V band waveguide to microstrip transitions filine structure

文章研制了一款V频段的波导微带转换器,该转换器采用对极鳍线过渡结构,并提出了一种抑制谐振及基片安装引起的高次模的设计方案。实际测试回波损耗小于-21 dB,插入损耗小于1.6 dB。

This paper developed a V band waveguide microstrip converter, which adopted the transition filine structure, and put forward the design scheme of a higher harmonic mode caused by substrate mounting and restraining resonance oscillation. The actual test return loss is less than -21 dB, the insertion loss is less than 1.6 dB.
