This paper presents a novel microwave oscillator incorporating a simple microstrip ring‐type resonant cell as its terminating resonance component. Reduced chip size, higher DC‐AC power efficiency, and superior harmonic characteristics can be achieved from the introduction of this type of compact microstrip ring resonator cell. The oscillator provides a second harmonic suppression of 26.51 dB and an output power of 2.046 dBm, with 28% efficiency at an oscillation frequency of 2.11 GHz. © 2006 Wiley Periodicals, Inc.
