Abstract

In this paper, a new technique to reduce the phase noise in microwave oscillators is proposed using the resonant characteristics of the Photonic Bandgap(PBG). We applied PBG structure to ground of the microstrip line resonator with the low Q(Quality factor). Therefore, we improved about 10 dBc in contrast to phase noise characteristic of the conventional microstrip line oscillator at 2.4 GHz ＠ 100 MHz offset. Output power is 7.09 dBm.

본 논문에서는 광전자 밴드갭의 공진 특성을 이용하여 마이크로웨이브 발진기에서 위상잡음을 줄이기 위한 새로운 구조를 제시하였다. 낮은 Q값을 가지고 있는 마이크로스트립 라인 공진기의 접지 면에 PBG 구조를 적용하였다. 그래서 2.4 GHz 대역의 100 KHz offset에서 기존의 마이크로스트립 라인 발진기의 위상잡음 특성에 비해 약 10 dBc 개선시킨 결과를 얻었다. 출력전력은 7.09 dBm을 획득하였다.
