Abstract:
To provide a transmission-line conversion structure for a millimeter-wave band capable of being easily manufactured with a small size without easily causing non-uniformity in characteristics in a wide band. A transmission-line conversion structure for a millimeter-wave band that connects a microstrip line ( 10 ), which includes a main conductor ( 12 ) formed on one surface of a dielectric substrate ( 11 ) and a ground conductor ( 13 ) formed on the other surface thereof, with a waveguide ( 20 ) has a waveguide structure in which a transmission line ( 31 ) having a predetermined length is formed so as to be surrounded by metal walls ( 32 ). The transmission line is filled with a dielectric material having a relative permittivity of greater than 1. The transmission-line conversion structure allows electronic waves of a millimeter-wave band in a longitudinal direction of the main conductor.
