초록

본 논문은 기판 직접형 도파관(SIW)에 complementary split ring resonator(CSRR)이 탑재된 저위상 잡음 발진기를 제안한다. SIW 캐비티의 unloaded Q-factor는 CSRR을 삽입하여 높아졌고, 그 값은 1960을 나타내고 있다. 높은 Q-factor를 나타내는 SIW 캐비티 공진기에 대한 이론적인 분석과 설계 과정이 제시되어 있으며, 설계된 회로가 11.3 dBm의 출력 파워와 1-MHz 오프셋에서 -127.9 dBc/Hz의 위상 잡음을 갖는 9.3 GHz의 신호를 발생시킴을 실험적으로 보여주고 있다.

A low phase-noise microwave oscillator is presented by a substrate integrated waveguide(SIW) loading a complementary split ring resonator(CSRR) in this paper. The unloaded $Q$-factor of the SIW cavity is increased by loading a complementary split ring resonator(CSRR) and its value exhibits 1960. It is theoretically and experimentally demonstrated that the proposed circuit generates 11.3 dBm of output power at 9.3 GHz and a phase-noise of -127.9 dBc/Hz at 1-MHz offset.
