Abstract

The invention provides a dual-polarization eight-wave-beam antenna for a mobile communication base station. The dual-polarization eight-wave-beam antenna comprises an antenna array, a Butler matrix power feed network, a power divider group and a metal substrate. The antenna array is located on the upper face of the metal substrate, and the Butler matrix power feed network and power dividers are located below the metal substrate. Eight narrow wave beams with fixed directivity are formed on the antenna in a horizontal direction, interferences among the eight wave beams are low, and each wave beam has two polarization manners. The antenna disclosed by the invention has the characteristics of high capacity, broad frequency band, low side band and wide radiation range. According to the invention, the defects that a fixed wide wave beam is commonly adopted for the antenna of the traditional mobile communication base station, space diversity is needed, the anti-jamming capacity is poor and the like are overcome, and the communication capacity of the mobile communication base station is improved.

Description

technical field [0001] The invention relates to an antenna for a mobile communication base station, in particular to a dual-polarized eight-beam antenna for a mobile communication base station with low side lobe in a mobile communication environment. Background technique [0002] The concept of multi-beam antennas first appeared in satellite communications. Multi-beam antennas are used on satellites to cover different areas with different beams. The multi-beam antennas used on satellites mainly include multi-beam lens antennas, multi-beam reflector antennas, and multi-beam phased array antennas. The operating frequencies of these antennas are all satellite communication frequency bands, and the technologies used are different for different frequencies. [0003] In the mobile communication system, the base station uses smart antenna technology to realize space division multiple access, which can increase the network coverage distance, expand the communication network system ...
