불균일분포 RC소자에 의한 정편각구동점 임피이던스의 최적실현 = Optimal Realization of Constnat-Argumet Driving-Point Impedance Using a Nonuiform Distributed RC Element

국문 초록 (Abstract)

불균일분포 RC소자와 집중 RC소자를 병용한 간단한 회로구성에 의하여 구동점임피치던스가 일정편각 θo을 값도록 실현하는 문제를 고찰하였다. 분포소자의 형상과 집중소자의 값을 조직적으로 변화시키면서 오차를 최소로 하는 최적설계법을 적용하였다. 그 결과 θo=30°, -60°의 경우에는 주파수가 1 : 100의 범위에서 편각오차 2.5° 내외의 것을, 또 θo=-45°의 경우에는 어떤 낮은 주파수이상의 전주파수범위에서 매우 평저한 주파수 특성을 얻을 수 있었다. The problem of realizing a driving-Point impedance, the argument, θo, of which is as constant as possible over a given frequency reange was considered. An optimal design technique was applied by varying systematically the shape of the distributed element and the parameter values of the lumped elements. As a result it was possible to make the argument over two decades of frequencies within-2.5° for θo=- 30° and -60° and very flat above a certain frequency for θo=-45°.

The problem of realizing a driving-Point impedance, the argument, $\theta$o, of which is as constant as possible over a given frequency reange was considered. An optimal design technique was applied by varying systematically the shape of the distributed element and the parameter values of the lumped elements. As a result it was possible to make the argument over two decades of frequencies within-2.5$^{\circ}$ for $\theta$o=- 30$^{\circ}$ and -60$^{\circ}$ and very flat above a certain frequency for $\theta$o=-45$^{\circ}$.
