초록

본 논문에서는 임의의 두께의 기판을 갖는 suspended stripline의 효율적인 계산을 위해 Yee cell의 내부에 두개의 유전체(공기와 기판)가 있을 때 사용할 수 있는 FDTD 수식을 유도하였으며 이를 이용하여 suspended stripline의 특성 임피던스와 유효유전율을 계산하였다. 이러한 계산결과를 이용해서 suspended stripline 5단 저역통과 필터를 설계하였고 이를 제작 측정하여 된 논문에서 제안된 FDTD법을 이용한 suspended stripline해석의 유용성을 입증하였다.

A simple and efficient analysis method of the suspended stripline using the finite-difference time-domain (FDTD) method is presented. New FDTD equations are derived using the contour path FDTD concept for the Yee cell which contains a dielectric sheet. The characteristic impedance and the effective dielectric constant of the suspended stripline are calculated using our proposed FDTD method. Using the calculated results, a 5-element lowpass filter is designed and fabricated. Our proposed FDTD method is validated by the measured data of the fabricated lowpass filter.
