Patent ID: 7057483

Claim:
A high-frequency circuit module characterized in that the high-frequency circuit module includes: a plurality of high-frequency circuit devices; and a phase shift circuit provided between adjacent ones of the plurality of high-frequency circuit devices; each said high-frequency circuit device includes: at least a dielectric member which can create a resonant state of an electromagnetic wave; a support member which surrounds the dielectric member and has a lower dielectric constant than that of the dielectric member; a shielding conductor surrounding the support member; at least a transmission line including a strip conductor disposed to face part of the dielectric member, an earth conductor layer disposed to face the strip conductor, and a transmission-line substrate interposed between the strip conductor and the earth conductor layer; and a coupling probe which is connected to the transmission line and has the input/output coupling function of input/output coupling with the dielectric member by an electromagnetic wave, the dielectric member is excited in the TM 11δ mode when it has a rectangular cross section or in the TM 01δ mode when it has a circular cross section, and the transmission line of each said high-frequency circuit device is connected to the phase shift circuit.
