A novel 4×4 ultra-wideband (UWB) Butler matrix based on using multilayer directional couplers and phase shifters is presented. The use of conductor-backed coplanar waveguide CB-CPW slot technique eliminates the crossovers needed in the conventional planar matrix leading to a significant size reduction and loss minimization. The proposed Butler matrix exhibits couplings and phase errors within −7 ± 1 dB and 11• over the entire bandwidth with a center frequency at 6.85 GHz. This matrix is suitable for ultra wideband communication systems.I.

“…Few years later, few types of coupler design have been proposed to offer broadband frequency coverage but unfortunately none of them manage to cover the whole ultra‐wideband frequency from 3.1 to 10.6 GHz. Table shows the summarization of the coupler mentioned previously in terms of the bandwidth.…”

An extended works of a diamond shaped 3 dB coupler design that is operating in ultra‐wideband frequency range is presented in this article. The proposed design is accomplished by using multilayer technology in which the structure is formed by three layers of conductors and interleaved by a layer of substrate between each one of the conductor layer. The proposed designed coupler simulation result shows that the design exhibits a coupling of 3 dB return loss and isolation better than 22 and 21 dB, respectively. Whereas, the phase difference performance is in the range of 90° ± 2° over the designated band. The coupler is fabricated and measured. Analysis studies on the parametric value are presented and discussed to observe the effect of the dimension of the patch to the performance of the coupler. © 2013 Wiley Periodicals, Inc.
