Abstract
Traditional microstrip line (MSL)-to-ridge gap waveguide (RGW) transition commonly sets the peripheral circuits to the same layer with the MSL for the reason the printed circuit board (PCB) is placed on the metal structure, which causes its inevitable limited integrability and inconvenience controllability. To overcome these demerits, the bottom of the PCB is used to supercede the conventional metal lid of the RGW in this letter. The proposed configuration uses an RGW bifurcated probe (BP) to convert the quasi-TEM mode into the TE101 mode in the resonator built by the plated-blind groove and cavity back. An MSL-modified monopole probe with a pair of irises is inserted in the resonator to couple the electric field (E-field) into the MSL. The methodology and mechanism of the transition are investigated and the manufactured back-to-back module verifies the feasibility of this transition. The transition allows the peripheral circuits to be placed on the flip side of the lid easily, which can significantly attenuate the adverse effects led by peripheral circuits, compact the size, and control the RGW circuits simultaneously.
传统的微带线(MSL)到脊隙波导(RGW)过渡通常将外围电路设置在与 MSL 相同的层上,原因是印刷电路板(PCB)放置在金属结构上,这就不可避免地造成了其有限的可集成性和不便的可控性。为了克服这些缺点,本文使用印刷电路板的底部来取代传统的 RGW 金属盖。建议的配置使用 RGW 分叉探针 (BP),在由电镀盲槽和腔背构建的谐振器中将准 TEM 模式转换为 TE101 模式。谐振器中插入了一个带有一对光圈的 MSL 改进型单极探针,将电场(E-场)耦合到 MSL 中。对过渡的方法和机制进行了研究,制造的背靠背模块验证了这种过渡的可行性。这种过渡可以方便地将外围电路放置在盖子的翻转面上,从而大大减弱外围电路带来的不利影响,缩小体积,并同时控制 RGW 电路。
