In this paper, Ku-band low phase noise oscillator using DSRR structure resonator based on metamaterial was proposed. To improve the phase noise of the oscillator, the proposed resonator consist of a DSRR strcuture based on metamaterial. The proposed resonator have a characteristic of $S_{11}$ is -0.25 dB, and $S_{21}$ in -44.59 dB at 14.67 GHz, respectively. At 14.67 GHz, the proposed Ku-band low phased oscillator achieves a output power of 2.03 dBm, $2^{nd}$ harmonic of -36.04 dBc, and phase noise of -130.63 dBc at the 100 kHz offset, respectively.
