A 9 GHz four beam antenna array fed by a Butler matrix is designed, fabricated and measured. Two 4×4 Butler matrices are addressed and compared in this work: (1) with and (2) without crossovers. It has been shown that this latter presents the best performances in terms of losses and complexity. The fabricated prototype (without crossovers) connected to four patch antennas exhibits good performance and allows the forming of four orthogonal uniform beams (at −46°, + 16°, −18° and +45°) with an effective coverage of 91°.
