Abstract

In this paper, the Square Split Ring Resonator(: SRR) of Defected Ground Structure(: DGS), applicable to MMIC(: Monolithic Microwave Integrated Circuit) design, is proposed. The mathematical method to solve the equivalent parameter of the resonator from the measured results of resonator is introduced in this paper. To verify the method, SRR-DGS resonator with 2.95 GHz center frequency is fabricated, for measuring characteristics and calculating the equivalent parameter. The result from this process is compared with the data of the ADS simulation, and as a result both were identical.

본 논문에서는 MMIC(: Monolithic Microwave Integrated Circuit) 설계에 적용 가능한 결함 접지면 구조의 사각 분리형 링 공진기를 제안한다. 본 논문에서는 공진기의 등가회로 파라미터를 공진기의 측정된 특성 값으로부터 수식적으로 계산하는 방법을 나타내었다. 본 논문에서 제안하는 방법을 검증하기 위해 공진주파수가 2.95 GHz인 결함 접지면 구조의 사각 분리형 링 공진기를 제작하여 특성을 측정하고 그것을 본 논문의 방법대로 등가 파라미터를 계산하였다. 이 결과를 시뮬레이션한 결과와 비교하여 일치함을 보였다.
