Modal phase velocity compensation in multilayer differentially fed directional couplers

摘要

Abstract >In this article, we present for the first time the possibility of the modal phase velocity compensation in differentially fed directional couplers designed in inhomogeneous dielectric media. It is shown that in an appropriate, inhomogeneous dielectric structure, the equalization of even‐ and odd‐mode phase velocities propagating in such couplers can be made. The presented method has been verified experimentally by design and measurements of a fabricated coupler to show the correctness and applicability of the proposed solution. A 8‐dB differentially fed directional coupler has been designed as a edgewise structure operating at 1 GHz center frequency. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs"
