Abstract	A high Q-factor substrate integrated waveguide (SIW) cavity resonator and its application of X-band low phase noise oscillator is proposed. Complementary split-ring resonators are used to improve the Q-factor of the proposed resonator. The size of the resonator is reduced by using quarter-mode circular SIW cavity. The oscillator based on the proposed SIW cavity resonator can be easily designed and tested. Measured results demonstrate an output frequency of 10.11 GHz and a phase noise of −108.7 dBc/Hz at 100 kHz offset. The oscillator is also able to deliver an output power of 4.6 dBm and harmonic rejection of better than 30 dBc. The proposed oscillator is suitable for low-cost high-frequency systems.
