Description
technical field [0001] The invention relates to wireless communication technology, in particular to a dual-polarized antenna unit and a base station antenna. Background technique [0002] Base station antennas play a pivotal role in mobile communications. In order to meet people's increasing demand for mobile communication bandwidth and speed, new communication systems and new equipment with higher speed and capacity are required. For example, the 65-degree base station antenna plays a key role in the coverage of suburban and urban dense areas. It It plays a positive role in improving system capacity and reducing inter-cell interference. Wherein, the 65-degree base station antenna refers to an antenna whose half-power lobe width can be equal to 65 degrees. [0003] In the prior art, the 65-degree base station antenna usually includes a +45 / -45-degree dual-polarized antenna unit, which is composed of four symmetrically placed half-wave symmetric oscillators, and two opposit...
