Abstract :
In this paper, a novel coupled transmission line coupler is proposed with compact size and increased design flexibility. The coupling characteristic of the coupler is given in closed-form formula through the even-odd analysis and the design methods are presented based on the analysis results. The advantages of the proposed structure are verified through actual design and measurement.
