Abstract

The invention relates to a dual-polarized high-isolation indoor distribution antenna. The antenna is characterized by comprising a vertical polarized antenna which comprises two semicircular copper sheets perpendicular to each other and a circular copper sheet located above the semicircular copper sheets, and feeds through a feed hole located in the center of a dielectric plate; the antenna further comprises a horizontally polarized antenna which is composed of two parts located on the upper surface and the lower surface of the dielectric plate, four printed dipoles, four arc parasitic patches and four metal strips are arranged on the upper surface of the dielectric plate, a one-to-four power divider is arranged on the lower surface of the dielectric plate, and a dumbbell-shaped structure formed by gaps and rectangular holes is arranged in the middle of the printed dipoles. The indoor distribution antenna can cover the frequency bands of 1.71 GHz to 2.69 GHz and 3.3 GHz to 3.6 GHz at the same time, is applied to 3G / LTE / 5G, and has the characteristics of high port isolation, low out-of-roundness and low profile.

Description

technical field [0001] The invention relates to the technical field of antennas suitable for wireless broadband communication systems, in particular to a dual-polarized high-isolation indoor distributed antenna. Background technique [0002] With the opening of large-scale commercial use of 5G, the application of 5G antennas has become common. While the frequency of the communication system is constantly evolving to 5G, the 2G / 3G / LTE frequency bands still play an important role in the evolution of communication technology. Indoor Internet access requires an indoor distribution system to transmit signals to the source and destination. In addition to the coverage of 5G signals, the signals in the 2G / 3G / LTE frequency bands also need to be reserved. Therefore, the development of coverage in the 2G / 3G / LTE / 5G frequency bands The antenna has a good application prospect. The indoor distributed antenna needs to have the characteristics of omnidirectional radiation, so that each sin...
