Abstract

The invention relates to an indoor distribution antenna. The antenna is characterized by comprising a horizontal polarization radiation unit, the horizontal polarization radiation unit is composed of two parts located on the top surface and the bottom surface of a dielectric plate, the bottom surface part comprises a circular patch, four pairs of inverted L-shaped patches, four T-shaped patches and four parasitic patches, the top surface part is provided with a one-to-four power divider; and the antenna further comprises a vertical polarization radiation unit which comprises eight E-shaped patches, a circular hollow patch and four metal sheets connected with the circular hollow patch and the horizontal polarization radiation unit. The indoor distribution antenna has the characteristics of low cross polarization level, high port isolation, low out-of-roundness, high gain 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 an indoor distributed antenna. Background technique [0002] With the arrival of the first year of 5G, it marks that 5G is about to be commercialized, and the frequency of the communication system is constantly evolving to high frequency. The frequency bands 1.71GHz-2.69GHz and 3.3GHz-3.6GHz have been allocated to communication systems as 2G / 3G / LTE / 5G. Indoor Internet access requires an indoor distribution system to transmit signals to the source and the sink. Since 5G has not been fully popularized, the 3G / LTE frequency band signals still need to be reserved, so a research that can be used in 3G / LTE / 5G at the same time An indoor distributed antenna is necessary. Indoor distributed antennas need a radiation mechanism with better out-of-roundness on the XOY plane, so that each sink can receive a good signal, so it is necessa...
