An integrated beamforming network and vibrator assembly and a multi-beam antenna

Abstract

This invention relates to the field of antenna equipment technology, and particularly to an integrated beamforming network and vibrator assembly and a multi-beam antenna. The assembly includes a three-beamforming network integrated on a circuit board. A vibrator array is mounted on the circuit board via mounting interfaces. Each row of the vibrator array includes five vibrator elements. The three-beamforming network includes a first 3×5 Butler matrix module and a second 3×5 Butler matrix module. Each output port of the first and second 3×5 Butler matrix modules is connected to a corresponding vibrator element. The first 3×5 Butler matrix module serves as the +45° polarization network of the three-beamforming network, and the second 3×5 Butler matrix module serves as the -45° polarization network. This invention can reduce the material cost and weight of the antenna, and the simplified connection improves the efficiency and pass rate of antenna production.
