本文介绍了一种改进的毫米波宽带双脊波导到同轴线过渡的设计方法。提出的设计是基于模式转换理论和阻抗匹配技术。利用全波分析软件分析和模拟了该器件的微波频率跃迁特性。根据模拟结果，制作了几个过渡层。在18 ~ 40 GHz的宽频带内，实验证实了预测的超宽带性能。
In this paper, an improved design method of millimeter wave wideband transition from double-ridge waveguide to coaxial line is introduced. The proposed design is based on the mode conversion theories and impedance matching techniques. The characteristics of the transition in microwave frequencies are analyzed and simulated by full-wave analysis software. According to the simulated results, a couple of transitions are fabricated. The predicted superduper performances have been confirmed experimentally in a wide frequency range of 18 ~ 40 GHz.
