摘要

本文对两个在伦敦国王学院制造的3db多层CPW定向耦合器进行了数值表征。利用二维有限元程序研究了耦合器的准瞬变电磁法模型。得到并验证了两种耦合器的偶/奇模特性阻抗。为了优化，还计算了两个耦合器的特性阻抗随耦合间隙的变化。

Numerical characterisation of multi-layered CPW directional couplers

This paper presents a numerical characterisation of two 3 dB multi-layered CPW directional couplers, which were fabricated at King's College London. The quasi TEM models of the couplers are studied with the help of a 2-dimensional finite element program. The characteristic impedances of even/odd modes for both couplers are obtained and verified. For the purpose of optimisation, the characteristic impedances varying with the coupling gaps in both couplers are also computed.
