Abstract
A high-frequency transmitter-receiver apparatus includes a transceiver circuit realized in a planar structure by a dielectric substrate and a semiconductor chip and a planar antenna formed on a dielectric substrate are provided on front and rear surfaces, respectively, of a single electrically conductive base plate. Signal lines of the planar circuit and the planar antenna are electrically interconnected by a coaxial line which extends through said base plate.
