Asymmetrical $4\times4$ Butler Matrix and its Application for Single Layer $8\times8$ Butler Matrix
IEEE Transactions on Antennas and Propagation, 2019The design procedure and measured results of a novel $4\times 4$ Butler matrix are presented in this paper. This asymmetrical structure provides fairly flexible phase outputs; therefore, the array radiation pattern can be rotated around the array normal axis.

Modelling and Validation of a Compact Planar Butler Matrix by Removing Crossover
Wireless Personal Communications, 2017In this work a compact planar butler matrix is presented by removing the 0 dB crossover. The proposed butler matrix consists of 45° and 90° phase shifter, and four branch line coupler miniaturised by employing open stubs in each transmission line. As the crossover is removed from the circuit, the circuit size is reduced and the performance is enhanced ...

Wideband Slot-Coupled Butler Matrix
IEEE Microwave and Wireless Components Letters, 2014We present a multilayer 4 × 4 Butler matrix based on corrugated slot-coupled structures, which operates over the complete UWB band (3.1 to 10.6 GHz) with excellent phase and amplitude performance. A prototype has been fabricated which covers the UWB band with a measured return loss better than 21 dB, an isolation better than 24 dB, an amplitude ...

Design of the Compact Planar Butler Matrix
2018 Asia-Pacific Microwave Conference (APMC), 2018A planar $4\times 4$ Butler matrix with a compact size is proposed. With the dual transmission lines, the proposed Butler matrix has arbitrary phase difference and phase delay for the used couplers and crossovers, respectively. In terms of experimental verification, the circuit size of the fabricated Butler matrix is $0.86\lambda_{g}\times 0.66\lambda_{
