Abstract

The present invention relates to a high-isolation dual polarization station antenna unit facing 5G application. The unit comprises a dielectric slab, a coaxial feeder, a back panel and an SMA feeder arranged in order from top to bottom. The front and back surfaces of the dielectric slab are etched with a first bow-tie dipole antenna and a second bow-tie dipole antenna which are vertically arrangedat +-45 degrees, each bow-tie dipole antenna is formed by two symmetrically arranged dipole antenna arms, and each dipole antenna arm comprises one optimized fractional parasitic structure. The high-isolation dual polarization station antenna unit facing 5G application forms a station antenna unit with low loss and high isolation features and low loss and high loss and high isolation through theoptimized fractional parasitic structure so as to reduce the loss of the antenna itself and reduce the self interference between antennas.

Description

technical field [0001] The invention relates to a dual-polarized base station antenna unit, in particular to a high-isolation dual-polarized base station antenna unit for 5G applications. Background technique [0002] In recent years, with the rapid development of wireless communication technology, people's desire for data rate is increasing day by day. Dual-polarized antennas are widely used in base station systems because they can achieve greater channel capacity and faster transmission rates. However, in a communication system, there is often a strong mutual coupling between the dual-polarized antennas of the base station antenna unit, and the self-interference caused by this will degrade the performance of the base station system. Therefore, it is essential to design a base station antenna unit with high polarization isolation. [0003] Research on high-isolation dual-polarization base station antenna units is ongoing at home and abroad, literature [1] (Mao Jianjun, Yu...
