Abstract
A compact high-frequency circuit device including a signal distribution circuit and a signal combining circuit. The high-frequency circuit device has a multilayer circuit, and the multilayer circuit includes a first conductor for transmitting a signal; a first dielectric layer in which the first conductor is embedded; a first ground conductor layer on one surface of the first dielectric layer and having a first opening; a second ground conductor layer on the other surface of the first dielectric layer and having another first opening, the first openings of the first and second ground conductor layers being mutually opposed; second dielectric layers, one being provided on the surface of the first ground conductor layer, and the other on the surface of the second ground conductors layer; and a pair of second conductors for transferring a signal, one being provided on the surface of one of the dielectric layers and the other on the surface of the other second dielectric layer, portions of the second conductors being mutually opposed at the first openings.
