Abstract
Provided is a dielectric waveguide filter. The filter includes: a multi-layered structure of dielectric substrates having first and second ground planes at its top and bottom; first, second, and third waveguide resonators disposed at multiple layers within the multi-layered structure; converters for signal transition between input/output ports and the first and third waveguide resonators; first vias for forming the first, second, and third waveguide resonators; and second vias disposed at a boundary surface of the first waveguide resonator and the third waveguide resonator.
