Synthesizing Microstrip Branch-Line Couplers With Predetermined Compact Size and Bandwidth

Abstract

A new method for designing the microstrip branch- line couplers with predetermined compact size and bandwidth is proposed in this paper. With the proposed approach, the size of the quarter-wavelength transmission line in the branch-line coupler can be reduced greatly. In addition, the proposed couplers can be easily fabricated on the printed circuit board… (More)
