초록

본 논문에서는 공진 MTM-TL(Metamaterial Transmission Line) 등가 회로를 이용하여 방사 및 회로 파라미터의 추출 식을 제시하였다. 특히 개방 또는 단락 상태에서 방사 소자인 직렬 $R_0$와 병렬 $G_0$를 EM 시뮬레이션 또는 측정을 통해 얻은 S-parameterd(|$S_{11}$|)를 이용하여 추출한다, EM 시뮬레이션의 결과, 추출한 파라미터를 이용한 회로 시뮬레이션의 결과 그리고 측정 결과가 매우 일치함을 확인하였다.

Some closed-form expressions for circuit parameters are derived based on the equivalent circuits for the resonant MTM-TL(open and short). The lumped series resistance and shunt conductance, which explain radiation effects of a unit cell may be found by |$S_{11}$|(simulated or measured) with open and short terminations, respectively. The EM-simulated results, circuit-simulated results(obtained using extracted circuit parameters) and measurement results are shown to be in good agreement.
