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%. © 2005 Wiley Periodicals, Inc.
