Abstract

In this work, a novel and miniaturized 4*4 Butler matrix will be presented. This proposed butler matrix comes with four 3 dB quadrature forward wave coupled line coupler, two 45 Schiffman phase shifter and one crossover. This BM has been created a centre frequency of 5.8 GHz using FR4 substrate. The crossover of this BM has substituted with a 0 dB. The proposed BM occupies a total area of (84.74 mm)*(76.56 mm). It exhibits high isolation and wideband 4x4 Butler matrix designed and simulated by employing a single-layer FR4 substrate. The return losses are better than 28 dB with its good performance
