ABSTRACT:
In a microwave oscillation apparatus including a negative resistance element, a microstrip line having a first end connected to the negative resistance element and a second end connected to a terminating resistor, and a dielectric resonator magnetically coupled to the microstrip line, a capacitive stub is provided on the microstrip line at a distance (1/4) .lambda..sub.s (2N-1) from the first end thereof, where .lambda..sub.s is a wavelength of a spurious oscillation frequency component and N is a positive integer.
