Embodiment

[0033] 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 present invention provides an omnidirectional indoor antenna for 5G communication, including a horizontal polarization unit, a vertical polarization unit, a dielectric board, and a feed network; the horizontal polarization unit is located on the dielectric board, and the dielectric board is circular The horizontal polarization unit is uniformly set outward with the center of the dielectric plate as the center of the circle, and the vertical polarization unit is located at the center of the horizontal polarization unit and is perpendicular to the horizontal polarization unit, that is, perpendicular to the dielectric plate; the horizontal polarization unit includes SMA feed Electric head, one-to-eight feed network, eight pairs of radiating dipoles, FR4 dielectric board, "sun"-shaped ground plane, eight pairs of parasitic patches, eight pairs of guide units; the vertical polarization unit includes SMA feed head, "Sun" shaped ground plane, "vase" shaped vertically polarized radiation structure. The antenna has low profile, wide impedance bandwidth, high isolation, high gain, low out-of-roundness, and low cross-polarization characteristics.

Description

[technical field] [0001] The invention relates to the technical field of antennas, in particular to an omnidirectional indoor antenna for a wireless broadband communication system. [Background technique] [0002] 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. [0003] 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 to increase chan...
