Abstract
A high-frequency oscillator includes: a substrate composed of a dielectric material; a first transmission line of coplanar structure which is arranged on one principal surface of the substrate; an amplifier having an input terminal and an output terminal and which is inserted into the first transmission line such that the input terminal and output terminal connect to the first transmission line; and a second transmission line which is provided on the other principal surface of the substrate, which electromagnetically couples with the first transmission line, and which constitutes a feedback circuit with respect to the amplifier. The first transmission line is typically a coplanar line of finite length, and the second transmission line is typically a microstrip line.
