Patent ID: 8564478

Claim:
A high-frequency module, comprising: a substrate comprising an input-output portion for high-frequency signal formed in one surface thereof; a circuit board which is located on the one surface of the substrate and comprises a dielectric waveguide line, an end face of the dielectric waveguide line being exposed at a lateral surface of the circuit board; and a resonator configured to resonate the high-frequency signal, the resonator comprising input-output end portions for high-frequency signals at both ends thereof, one of the input-output end portions being connected to the end face of the dielectric waveguide line and the other of the input-output end portions being connected to the input-output portion of the substrate, wherein a virtual plane extending from the end face intersects with the one surface of the substrate, wherein the resonator is constructed of a cavity resonator having openings opened at ends thereof, and one end-side opening is connected to an end face of the dielectric waveguide line in a high-frequency signal transmission direction, and the other end-side opening is connected to an input-output port of the substrate.
