DOI: 10.1109/tmtt.2016.2623709
Abstract: We propose a novel, eight-port, forward-wave directional coupler with periodically patterned ground structures. The input impedances of the four modes for the proposed coupler can be matched, and the phase difference between the even–even and… read more here.
