Abstract

In this paper, we propose a S-band oscillator with a reduced electrical size by applying a vertical split ring resonator(VSRR). The VSRR is a type of split ring resonator that operates as a resonator by the capacitance and inductance generated between the microstrip lines arranged on the top and bottom of the dielectric substrate and it has an advantage that the electrical size of the resonance circuit can be reduced as compared with the conventional ring resonator. In this paper, we design a VSRR operating over S-band and an oscillator using the VSRR as the resonant circuit. The proposed oscillator showed the output of 5.9dBm at 2.4HGz and showed the phase noise characteristics of -112.58dBc at 100KHz offset frequency and -117.85dBc at 1MHz offset.

본 논문에서는 수직 분할 링 공진기(VSRR, Vertical Split Ring Resonator)를 적용하여 전기적 크기를 축소시킨 발진기를 제안하였다. VSRR은 유전체 기판의 상면과 하면에 일렬로 놓인 마이크로스트립 라인간에 발생하는 커패시턴스와 인덕턴스에 의해서 공진기로 동작하는 분리형 링 공진기(Split Ring Resonator)형태이며, 마이크로스트립 라인을 이용한 일반적인 hairpin 형태 또는 평면형 링 공진기에 비해 공진 회로의 전기적 크기를 축소할 수 있는 장점이 있다. 본 논문에서는 S-band에서 동작하는 VSRR을 설계하고, 이를 공진회로로 사용한 발진기를 설계 및 구현한 결과를 제시하였다. 제안된 발진기는 2.4GHz에서 5.9dBm의 출력을 나타내었으며, 오프셋 주파수 100kHz에서 -112.58dBc@Hz, 1MHz에서 -137.36dBc@Hz의 위상잡음 특성을 나타내었다.
