Abstract
A dielectric waveguide filter includes at least four dielectric waveguide resonators arranged along a main coupling path for signal propagation, and main coupling portions each of which is provided between the dielectric waveguide resonators that are adjacent to each other along the main coupling path among the at least four dielectric waveguide resonators. The main coupling portions include an inductive coupling portion and a capacitive coupling portion, and the inductive coupling portion and the capacitive coupling portion are alternately and repeatedly arranged along the main coupling path.
