The invention discloses a dual-polarization multi-frequency ultra-wideband base station antenna. The antenna comprises a reflecting plate (1), a dielectric substrate (2), an impedance adjusting cylinder (3), a middle-layer resonance plate (4), an L-shaped feeding piece (5), an impedance matching cylinder (6), a supporting cylinder (7) and a coaxial feeder line (8). The L-shaped feed piece (5) is printed on the upper surface of the dielectric substrate (2); symmetric oscillators are printed on the lower surface of the dielectric substrate (2), and the impedance matching cylinder (6) is welded at terminals of the symmetric oscillators. The middle-layer resonance plate (4) supports the dielectric substrate (2) through the supporting cylinder (7), and the reflecting plate (1) supports the middle-layer resonance plate (4) through the supporting cylinder (7). The antenna has the advantages of being small in size, large in frequency range, simple in structure, easy to process and the like, and is applied to a 5G novel base station, so that the antenna installation space can be greatly saved, and a foundation is laid for the deployment of a 5G high-frequency antenna.
Description
technical field [0001] The invention relates to the technical field of antennas, and relates to a dual-polarized multi-frequency ultra-wideband base station antenna. Background technique [0002] With the improvement of 5G standards, the deployment of new base stations that meet the requirements of the times is imminent. In the face of new requirements such as low latency and high user experience rate proposed by 3GPP for the 5G era, the deployment of large-scale antenna array base station antennas has become the main solution in the industry. However, due to the limitation of sky space and tower resources, how to deploy 5G base stations while saving costs as much as possible has become one of the urgent problems to be solved. At present, in the 4G base stations deployed on the existing network, the base station antennas in the 1427MHz-2690MHz frequency band mainly use two antenna units with different structures to work together through space diversity arrangement. For the ...
