Design of Ku-band Low Phase Noise Oscillator Using DSRR Structure Resonator based on Metamaterial

Abstract

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 S11 is -0.25 dB, and S21 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.
