A Novel Oscillator with very Low Phase Noise using Double H-shape Metamaterial Resonator

초록

In this article, an oscillator (OSC) in X-band with a double H-shape metamaterial resonator (DHMR) based on high-Q is proposed with metamaterial (MTM) structure to improve the phase noise and the output power. The proposed OSC has been exhibited low phase noise and high output power for good performance of the frequency synthesizer. The DHMR is designed to be high-Q at resonance frequency through strong coupling of E-field. This character makes phase noise excellent. The OSC using DHMR is designed in X-band so as to apply frequency synthesizer of radar systems. The output power is 7.33 dBm and the phase noise is -108 dBc/Hz at 100 kHz offset of carrier frequency.
