Abstract: An antenna module is an antenna module including at least a first radiation electrode, and a first power feeding electrode coupled with the first radiation electrode, and includes: a first dielectric layer including the first power feeding electrode; and a second dielectric layer disposed at one side of the first dielectric layer in a thickness direction of the first power feeding electrode, and a fracture toughness value of the second dielectric layer is larger than a fracture toughness value of the first dielectric layer.

Abstract: A filter includes a first port, a second port, a path, a circuit part, and at least one cavity resonator. The path connects the first port and the second port. The circuit part is provided in the path. Each of the at least one cavity resonator is coupled with the path from an outside of the path in a circuit configuration. The first cavity resonator is coupled with the path between the first port and the circuit part. The second cavity resonator is coupled with the path between the second port and the circuit part.
