Abstract
Electrodes are formed on both surfaces of a dielectric plate. Openings are formed in the electrodes such that pairs of openings face each other through the dielectric plate. Each pair of electrode openings defines a resonator. The resonators positioned at the ends of the dielectric plate are directly coupled to a waveguide formed by a package base and a package cover.
