Line coupler is presented. The adoption of such technologies adds degrees of freedom with respect to other already proposed design techniques, thus allowing the development of a very compact device, and a larger flexibility in the choice of the two operating frequencies and corresponding bandwidths.

## 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 new dual‐band operation scheme is proposed for the branch‐line coupler using two center‐tapped branches. The proposed coupler has two branches with a stub line attached at the center. Only two stubs are required for the dual‐band operation, which reduces the circuit complexity and min
## Abstract A dual‐band (DB) composite right/left‐handed (CRLH) branch‐line coupler implemented in metal–insulator–metal technology is presented. A simple and accurate circuit‐model design procedure for DB CRLH transmission lines is described and applied to the coupler. A prototype operating at 4.2
