An air-filled mode selective transmission line (AF-MSTL) consisting of an opened groove gap waveguide (GWG) and an inverted coplanar waveguide (CPW) is proposed in this letter. By using the electromagnetic band gap (EBG) structure, the electrical contacts of AF-MSTL are not required during the assembly process. To verify the design, the AF-MSTL prototype, connected to two designed grounded-CPW (GCPW) to AF-MSTL transitions to build a back-to-back structure, has been fabricated and measured. A measured insertion loss of 0.2857 dB/mm at 110 GHz is achieved, which is lower than the dielectric filled (DF) MSTL of 0.5012 dB/mm at 110 GHz.

非接触式充气模式选择性传输线

本文提出了一种由开槽间隙波导(GWG)和倒置共面波导(CPW)组成的充气模式选择传输线(AF-MSTL)。通过使用电磁带隙 (EBG) 结构,AF-MSTL 的电触点在组装过程中不需要。为了验证该设计,AF-MSTL 原型已被制造和测量,该原型连接到两个设计的接地 CPW (GCPW) 到 AF-MSTL 转换以构建背靠背结构。在 110 GHz 时测得的插入损耗为 0.2857 dB/mm,低于 110 GHz 时 0.5012 dB/mm 的电介质填充 (DF) MSTL。
