Abstract
Abstract A microwave oscillator circuit comprises a micro-strip line having a substrate of a dielectric material, a semiconductor such as a Gunn diode or an FET, and a dielectric resonator connected to the micro-strip line as a resonator circuit. A hole is formed in the substrate beside the micro-strip line, or the substrate is cut off to provide a recess. Through this hole or recess, as the case may be, the dielectric resonator is directly secured to the metal casing supporting the micro-strip line on the opposite side thereof or to the grounding conductor of the micro-strip line.
