Title:
BROADBAND NINE-BEAM ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2019/184008
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications antennas, and specifically relates to a broadband nine-beam array antenna. The present invention comprises a metal reflective panel, a radiating element array, a beamforming network, a first power divider network, a second power divider network, and a phase compensation circuit; said radiating element array is connected to the second power divider network and fixedly mounted on the metal reflective panel; said beamforming network is connected to said first power divider network by means of said phase compensation circuit and is fixedly mounted on the metal reflective plate. The invention has better side lobe and grating lobe suppression performance in an ultra-wide frequency band, reducing the adjacent-cell interference of a cell corresponding to the beam. In comparison with a five-beam antenna, the nine-beam antenna of the present invention achieves more cell splitting in the same spatial range, and achieves more frequency reuse of adjacent cells without increasing the number of antenna sites, thus further increasing network capacity.
