摘要

提出了一种新的分支线定向耦合器，以实现更宽的带宽。该器件采用脊波导实现，利用其宽单模带。它既可以在空脊波导中实现，也可以在LTCC中实现，以便集成在芯片模块中。按照系统的程序设计了两个分支和五个分支的原型。适当的等效电路提供初始尺寸，并通过基于严格有效的模式匹配方法的最终全波优化获得所需的最佳响应。利用HFSS软件的有限元方法对结果进行验证，并将制作样机进行测试

Ridge waveguide branch-line directional couplers for wideband applications and LTCC technology

A new branch-line directional coupler is proposed for achieving wide bandwidth. The device is implemented in ridge waveguide to exploit its wide monomode band. It can be physically realized either in empty ridge waveguide or in LTCC for integration in a chip module. Two prototypes of two and five branches are designed following a systematic procedure. An appropriate equivalent circuit provides initial dimensions and the desired optimum response is obtained by means of a final full-wave optimization based on the rigorous and efficient mode-matching method. The results are verified with the finite element method of the HFSS software and a prototype will be manufactured for testing
