Design of the Broad-Band 3-dB Branch-Line Directional Coupler Using Exponential Transmission Line
지수함수적인 비균일 전송선을 이용한 광대역 3-dB 브랜치라인 방향성 결합기의 설계
Abstract
A broad-band 3-dB directional coupler is implemented by using cascaded exponential transmission line as branch lines. Compared with that of the uniform transmission line, the bandwidth of the proposed 3-dB branch-line directional cpoupler increases 2.96 times.
