초록

본 논문에서는 두꺼운 외부도체를 가진 손실이 있는 동축선로의 해석적인 특성임피선스 표현식 및 근사식을 제안했다. 그리고 제안된 근사식을 동축선로의 동작 주파수대역에서 사용 가능하다는 것을 3.5mm reference air line에 대해 보였다.

In this paper, a closed exact from and its approximation of the characteristic impedance of a lossy coaxial line with a thick outer conductor are proposed. It is also shown for 3.5mm reference air line that the proposed approximation is accurate over the entire operating frequency range of the line.
