In this paper, a novel 3‐dB CPW multilayer slot‐coupled directional coupler is presented and implemented. The coupler has two CPW lines coupled through a hexagonal slot etched on a common ground plane located between these lines. To increase the coupling between these CPW lines, a slot with sharp edges is used. The proposed directional coupler showed promising results, especially in terms of bandwidth (∼6 GHz). The simulated results are also compared with the measured data, and a good agreement is reported. © 2006 Wiley Periodicals, Inc.
