In this paper, a microwave oscillator using the periodic stepped impedance ring resonator (PSIRR) is presented. The PSIRR has the compact size, harmonic suppression and high Q factor. The fabricated PSIRR oscillator has been reduced size of 18% and improved phase noise of 10dBc/Hz at the 100kHz Offset compared with conventional oscillator using microstrip.
