Abstract

In this paper, we proposed the method of the characteristic impedance and effective dielectric constant calculations of a parallel-two-wire transmission line coated with multi-layer dielectric material using conformal mapping method. First of all, we calculated the capacitance of the transmission line when coated by N layer dielectric material which has different thickness and dielectric constant and calculated the characteristic impedance and effective dielectric constant using calculated capacitances. When compared with the Maxwell 2D (made by Ansoft Corporation) simulation result calculated result was very similar to the simulation result within the four percent error range.

본 논문에서는 등각사상 법을 이용해 유전체가 다층으로 코팅된 평행 2선식 전송선로의 특성임피던스 및 유효 유전상수 등을 계산하는 방법을 제안하였다. 먼저 두께 및 유전상수가 다른 유전체가 임의의 N 층으로 코팅되었을 때 평행 2선식 전송선로의 정전용량을 계산하였으며, 이를 이용해 임피던스 및 유효 유전상수 등을 계산하였다. Ansoft 사의 Maxwell 2D를 이용한 시뮬레이션 결과와 비교하였을 때, 계산 결과가 오차범위 4% 이내로 거의 일치함을 알 수 있었다.
