| 摘要 |
The present invention relates to a dual-polarization five-beam antenna for a mobile communication base station, which comprises a metal floor board, at least 6 lines of linear antenna arrays parallel to each other, at least 6 first power dividers, at least 6 second power dividers, a first Butler-matrix feed network, and a second Butler-matrix feed network. Each line of linear antenna array is formed of at least 2 same antenna radiation units. The antenna structure of the present invention is capable of forming 5 dual-polarization beams with fixed orientations in the horizontal direction and forming a single dual-polarization beam with a fixed orientation in the vertical direction. The interferences among the 5 beams in the horizontal direction are low. The five-beam antenna fabricated according to the technical solution of the present invention has stable performance and large signal capacity, is easy to install, and can effectively lower the cost and well meet user requirements.
