✦ Synopsis
In this paper, we design and fabricate a 180°hybrid ring coupler in order to prove the fabrication possibilities of various passive components, by applying millimeter waves using newly proposed transmission lines, that is, dialectric-supported air-gapped microstriplines (DAMLs). In order to reduce the size of the hybrid ring coupler, we design it with an inserted slow-wave structure. With this structure, we were able to reduce the hybrid ring coupler's area by 33%.
