## Abstract A compact branch line coupler (BLC) using four coupled transmission lines is introduced. The loaded part of the proposed model has a same performance with a cascade two unit elements and it is equaled by a quarter wavelength line. The quarter wavelength lines of each branch in the conve

## Abstract In this article, an extremely compact dual‐band branch‐line coupler is presented. The miniaturized design saved 74% circuit dimension comparing to the original dual‐band branch‐line coupler. Several design methods and miniaturization techniques were involved in this study to achieve the

## Abstract A compact ring Branch‐Line Coupler (BLC) with size reduction of about 50%(in circuit area) of conventional BLCs at frequency 2 GHz is introduced. The coupler is designed by using nonuniform transmission lines (NTL) instead of Uniform Transmission Lines in each arm. The normalized width
