摘要： 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.

摘要： An oscillator with a dielectric resonator capable of providing a designated output and being suited for mass production comprising an insulating substrate, a strip structure, a dielectric resonator located adjacent to the strip structure, the last two being mounted on the substrate, and an oscillatory transistor connected to one end of the strip structure. The strip structure consists of two spaced strip sections interconnected by an electrically-conductive bridge-shaped connector section having a conductor part, which is located further away from the insulating substrate and closer to the dielectric resonator than the two strip sections.
