Abstract: Antennas are provided. An antenna includes an antenna array having a plurality of sub-arrays that each include a plurality of radiating elements. Moreover, the antenna includes a multi-stage beamforming network having a first stage including a plurality of first Butler matrices and a second stage including a plurality of second Butler matrices that are coupled between the first Butler matrices and the sub-arrays. The first Butler matrices are each coupled to each of the second Butler matrices. The second Butler matrices are coupled to the sub-arrays, respectively, without any cables between the second Butler matrices and the sub-arrays.
