摘要

本文基于新型间隙波导传输线技术，设计了一种宽带的0 dB前向波定向耦合器，提出的耦合器中心频率在30 GHz，可以实现宽带平坦的0 dB耦合特性，通过在两个相邻

Abstract

In this paper

a broadband 0 dB forward wave directional coupler is designed based on the new gap waveguide transmission line technology. The center frequency of the proposed coupler is 30 GHz

which can realize broadband flat 0 dB coupling level. The energy coupling from the main channel to the auxiliary channel is realized by multi coupling slots on the common wall of two adjacent groove gap waveguides. For the convenience of experimental measurement and verification

the transition from groove gap waveguide to standard WR-28 waveguide is designed. Finally

the designed coupler is manufactured and measured. According to the measurement results

the proposed directional coupler working frequency band is 27.1~31.5 GHz and maximum insertion loss is about 0.5 dB

the return loss is less than

and relative bandwidth is about 14.7% (center frequency is 30 GHz). The simulated result and measurement result agree well with each other

and the correctness of the design method is verified by experiments.
