这封信中提出了一种毫米波频率下波导到微带转换的设计。它依次具有两个主要转变。选择E平面探头来进行从波导到悬线的转换。然后，利用印刷电路板上的过渡图案将悬线转变为屏蔽微带线。为了完成设计，引入了金属缓冲器用于屏蔽微带线和微带线之间的转换。根据数值模拟的结果提出了 W 波段的拟议过渡。为了验证的目的，测量背靠背连接中的两个转变。结果表明，所提出的波导到微带过渡具有插入损耗低、回波损耗好、宽带特性以及毫米波频率下性能稳定等优点。
A design for waveguide-to-microstrip transitions at millimeter-wave frequencies is proposed in this letter. It features two major transformations in sequence. An E -plane probe is chosen to conduct the transformation from waveguide to a suspended line. Then, a transitional pattern on the printed circuit board is employed to transform the suspended line into a shielded microstrip line. To complete the design, a metallic buffer is introduced for the transformation between the shielded microstrip line and a microstrip line. A proposed transition at W-band is presented based on the results from numerical simulations. Two of the transitions in back-to-back connection are measured for the purpose of verification. The results show that the proposed waveguide-to-microstrip transition can offer the advantages of low insertion loss, good return loss, broadband nature, and stable performance at millimeter-wave frequencies.
