A Novel Miniaturized Forward-Wave Directional Coupler With Periodical Mushroom-Shaped Ground Plane

A novel miniaturized forward-wave directional coupler with periodical mushroom-shaped ground plane is proposed. The coupler can be designed with identical characteristic impedances for even and odd mode and enhanced the difference of propagation constants between the even and odd mode. These distinc...
