摘要

在印刷电路板(PCB)上实现电磁带隙(EBG)结构，作为波导法兰之间的垫片。所提出的衬垫可以减少由于波导法兰错位造成的泄漏。本文提出了一个WR-6.5波导的概念验证演示，覆盖110 - 170 GHz，回波损耗低于12 dB，法兰之间的气隙超过75 um。

A Compact PCB Gasket for Waveguide Leakage Suppression at 110-170 GHz

An electromagnetic bandgap (EBG) structure is implemented on a printed-circuit board (PCB) as gasket between waveguide flanges. The proposed gasket can reduce leakage between waveguide flanges due to misalignment. A WR-6.5 waveguide proof-of-concept demonstration is presented in this paper covering 110 - 170 GHz with a return loss lower than 12 dB and over a 75 um of air gap between the flanges.
