결합삼각함수 선로와 그 응용

Coupled Trigonomotric Transmission Line and its Application

일반적인 결합불균일선로에 대한 이론을 적용하여 결합삼각함수선로(CTTL)의 특성을 연구하였다. 우선 CTTL의 4-Port 전달메이트릭스 퍼래미터를 유도한 다음 이것을 사용하여 CTTL을 이용한 전역통과회로와 방향통합전압을 해석하였다. 선로에 연한 결합계수의 변화에 따라서 전역통도관로의 위상특성과 방향성결합기의 결합전압의 크기의 변화를 상세하게 연구하였다. 최후로 CTTL를 사용한 광대역 90° 차동위상추이기와 고역통과 방향성통합기의 설계예를 들고 그 실현방법을 고찰하였다. Characteristics of coupled trigonometric transmission lines (CTTL) are studies based on the theory of general coupled nonuniform transmission lines. First, the 4-port transmission matrix parameters of networks and directional couplers using CTTL. The phase slrift characteristic of the all-pass networks and the magnitude characteristic of the directional couplers are studied in detail for various coupling and a high-pass small ripple directional coupler using CTTL are given and their physical realization is considered.
