By using short‐circuited Composite Right/Left‐Handed Transmission Lines as loading stubs, and Purely Right‐Handed Artificial Transmission Lines, a Dual‐Band Branch‐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. © 2007 Wiley Periodicals, Inc.
