This article presents a novel design of a 4 × 4 two‐layer wideband Butler matrix using slot coupled directional couplers and wideband crossover. With this new configuration, the proposed matrix was designed to minimize the number of crossovers for reducing the size, the loss of the network and the complexity of the design, which leads with a broad bandwidth of ∼1.5 GHz. A four‐antenna array was connected to the matrix to build a beam‐forming system for beam steering. As a result, four orthogonal beams are produced at −45°, −15°, 15°, and 45°. This matrix is suitable for wideband communication systems. © 2009 Wiley Periodicals, Inc.
