Abstract
A microwave oscillator of the type in which a dielectric resonator is disposed inside a conductive housing, characterized in that a conductive rod-like member is disposed inside the housing and arranged in parallel with the axis of the dielectric resonator with one end connected electrically to the housing and the other end left free. Preferrably, the rod-like member is made so thin as to interrupt little the magnetic flux generated by the dielectric resonator, and the resonance frequency of the housing is selected lower than that of the dielectric resonator.
