Wideband butler matrix in microstrip-slot technology


The design of a 4 × 4 Butler Matrix for use in a multi-beam antenna array operating over wide frequency band is presented. In order to achieve wideband characteristics, the matrix uses microstrip-slot technology that employs two microstrip dielectric layers with a common ground plane and a coupling slot. The designed beamforming network is compact in… (More)
