초록

본 논문에서는 메타구조기반의 double split ring resonator (DSRR) 구조의 공진기를 이용한 Ku대역에서 낮은 위상 잡음 특성을 갖는 발진기를 제안하였다. 제안한 공진기는 대역저지 특성을 가지며 14.67 GHz에서 $S_{11}$은 -0.25 dB, $S_{21}$은 -44.59 dB를 나타내었다. 제안한 메타구조 기반의 공진기를 이용하여 설계한 발진기의 낮은 위상잡음 특성을 확인하였다. 제안한 메타구조 기반의 공진기를 적용한 발진기는 14.67 GHz에서 1차 발진이 일어나고, 100 kHz offset에서 -130.63 dBc의 낮은 위상잡음 특성과 출력전력 2.03 dBm, -36.04 dBc의 고조파 특성을 나타내었다.

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.
