Abstract
Traveling-wave directional filters (DFs) with multiple coupling slots are disclosed. A traveling-wave directional filter may include two terminating conductive strips in a top circuit layer of a substrate, a loop resonator in a bottom layer of a substrate, and a shared ground plane. Coupling slots in the ground plane may couple the conductive strips via the loop resonator.
