Abstract

The present disclosure relates to an antenna device and relates to the technical field of communication. The antenna device of the present disclosure includes: a first antenna unit, a second antenna unit, a third antenna unit and a main reflector are arranged at intervals along the central axis of the antenna device; the first antenna unit includes: a first pole working in a preset frequency band The oscillator and the oscillator reflector in the polarization direction; the second antenna unit includes: the oscillator working in the second polarization direction of the preset frequency band; the second polarization direction is perpendicular to the first polarization direction; the third antenna unit includes: working in An omnidirectional antenna dipole on at least one frequency band different from the preset frequency band; the main reflector acts on the signals sent by the second antenna unit and the third antenna unit.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to an antenna device. Background technique [0002] With the development of my country's 5G mobile communication technology, people have higher and higher requirements for wireless communication quality, and more than 70% of data services occur indoors, so the construction of indoor coverage systems is particularly important and urgent. The performance of the indoor coverage system ceiling antenna directly affects the room division effect and construction cost. [0003] At present, the existing antennas generally only support 800M-2700M single-polarization and dual-polarization omnidirectional ceiling antennas, and cannot support the 3300-3600M frequency band of 5G. Contents of the invention [0004] The inventor found that: in order to adapt to the arrival of the 5G era, it is necessary to design a new highly integrated indoor antenna device, which can not on...
