摘　　要：An oscillator(OSC)with a metamaterial resonator based on high-Q is designed to improve the phase noise in Kband.The proposed metamaterial resonator is a lattice structure resonator(LSR)that is designed to be high-Q by a strong coupling of E-field at the resonance frequency.Thus the output of OSC is about 12.5dBm at the f0.The phase noise is 109.477dBc/Hz at 100kHz offset frequency.An oscillator （OSC） with a metamaterial resonator based on high-Q is designed to improve the phase noise in K-band. The proposed metamaterial resonator is a lattice structure resonator （LSR） that is designed to be high-Q by a strong coupling of E-field at the resonance frequency. Thus the output of OSC is about 12.5 dBm at the f0. The phase noise is - 109.477 dBc/Hz at 100 kHz offset frequency.
