Abstract
A microwave resonance circuit device including plural microstrip lines provided on one side of a dielectric substrate. A dielectric resonator is mounted on the reverse side of the substrate from the microstrip lines and is disposed so as to have a coupling relation with a first one of the microstrip lines. A ground conductor is arranged on the reverse side of the substrate so as to overlap substantially one-half of the width of the first microstrip line extending in a direction away from the dielectric resonator, and to overlap entirely the other microstrip lines. A transistor is mounted on the same side of the substrate as the microstrip lines and connected therewith to form an oscillator circuit.
