Embodiment

[0038] Such as figure 1 , 2 As shown, the antenna mainly includes two parts: a horizontally polarized part and a vertically polarized part. The horizontal polarization part includes SMA feed head, one-to-eight feed network, four pairs of radiation dipoles at the top and bottom, dielectric plate 3, "sun"-shaped ground plane 10, eight pairs of parasitic patches 7, and eight pairs of guiding units 6. The vertically polarized part includes an SMA feed head, a "sun"-shaped ground plane 10, and a "vase"-shaped vertically polarized radiation structure 1. The horizontal polarization unit is located on the dielectric plate 3, the dielectric plate 3 is circular, and the horizontal polarization unit is evenly arranged outwards with the center of the dielectric plate 3 as the center of the circle, and the vertical polarization unit is located at the center of the horizontal polarization unit and vertically To the horizontal polarization unit, that is, to be perpendicular to the dielectr...

Abstract

The invention provides an omnidirectional indoor distribution antenna applied to 5G communication. The omnidirectional indoor distribution antenna comprises horizontal polarization units, a vertical polarization unit, a dielectric plate and a feed network, wherein the horizontal polarization units are located on the dielectric plate; the dielectric plate is in a round form; the horizontal polarization units are uniformly arranged outwards by taking the center of the dielectric plate as the circle center; the vertical polarization unit is located at the circle center of the horizontal polarization units and is vertical to the horizontal polarization units, that is to say, the vertical polarization unit is vertical to the dielectric plate; each horizontal polarization unit comprises an SMA feed head, a 1-to-8 feed network, eight pairs of radiation dipoles, an FR4 dielectric plate, a ground plane shaped like the sun, eight pairs of parasitic patches and eight pairs of leading units; and the vertical polarization unit comprises the SMA feed head, the ground plane shaped like the sun and a vertical polarization radiation structure shaped like a vase. The antenna has the characteristicsof a low profile, a large impedance bandwidth, high isolation, high gain, low out-of-roundness and low cross polarization.

Description

[0001] [technical field] [0002] The invention relates to the technical field of antennas, in particular to an omnidirectional indoor antenna for a wireless broadband communication system. [0003] [Background technique] [0004] On November 15, 2017, the Ministry of Industry and Information Technology of China took the lead in officially releasing the fifth-generation mobile communication system (5G) low-frequency band standard (3.3-3.6GHz; 4.8-5GHz) ("About the fifth-generation mobile communication system using 3300 -3600MHz and 4800-5000MHz frequency band-related matters"), the release of this communication standard marks the beginning of 5G communication commercial use in my country, and the 5G era is coming. Therefore, it is necessary to study 5G antennas under this background. [0005] In addition, the omnidirectional antenna has the advantage of 360-degree full coverage, which can avoid the existence of signal blind spots, and the dual-polarized antenna has the ability t...
