Abstract
In this paper, Designed Quadrature hybrid coupler apply Open-PI equivalent transmission line. Using the proposed structure we achieve significant size reduction with the same results of conventional quadrature hybrid coupler at 912MHz. The measured frequency responses agree well with simulated one.
