Novel airborne antenna for 5G network connection unmanned aerial vehicle CPE

Abstract

The invention discloses a novel airborne antenna for a 5G network connection unmanned aerial vehicle CPE. The antenna is of a three-section type structure and comprises a base, a plate-shaped antenna cover and an elliptical plate antenna cover which are connected together, the elliptical base is located at the top and provided with an installation hole and two feeder connectors, and the antenna is of a dual-polarization structure, that is, the two feeder connectors correspond to two different polarization directions of an orthogonal polarization mode; the omnidirectional whip antenna has the advantages that the networking structure requirement of a cellular network is met, the problem of air coverage of a common omnidirectional whip antenna at present is solved, the antenna is continuous and stable in coverage from the center of a cell to the edge of the cell, the signal quality from the top of a station to the edge of the cell meets the requirement, and the antenna has a wide application prospect. And a good and reliable antenna guarantee can be provided for air coverage networking.

Description

technical field [0001] The invention belongs to the field of communication technologies, and in particular relates to a novel airborne antenna for 5G network-connected unmanned aerial vehicle CPE. Background technique [0002] At present, with the development of UAV products and technologies, UAVs are playing an increasingly important role in various aspects of industry, military, transportation, and public security. When the UAV takes off, the ground control information of the UAV, the status information of the UAV in the air and the information collected by the equipment mounted on the UAV need to be transmitted through the data link between the ground and the air. At present, the 5G frequency band used by the network-connected 5G drones is the operator's 5G frequency band, which belongs to the Sub6G frequency band, with a specific frequency range of 2.6GHz to 5.0GHz. The solution of the UAV data link is to build a base station network covering the air like the ground mob...

AI Technical Summary

Problems solved by technology

And with the continuous expansion of 5G technology and networks, networked drones have also developed to the 5G stage, that is, both ground base stations and terminal equipment on drones have developed into 5G products, but currently there is no suitable 5G airborne antenna available; At present, 5G network drones do not have specially designed airborne antennas, and only use common whip-shaped omnidirectional antenna products as airborne antennas. Such antennas have many problems for 5G ground-air coverage: 5G airborne The CPE supports 2T4R and needs to be configured with 4 antennas for reception. When using a whip omnidirectional antenna, 4 antennas need to be installed, and since the 4 antennas are all vertically polarized, the antennas must have a large distance, otherwise the diversity effect will be affected.

[0006] 1. The rod antenna is a single-polarized antenna, and 5G terminals usually support 2T4R, so multiple rod antennas need to be installed;

[0007] 2. The rod antenna is vertically polarized, and the polarization diversity effect cannot be produced between multiple antennas. In order to improve the space diversity gain, a large distance between the antennas is required;

[0008] 3. The vertical lobe of the ordinary rod antenna has a large number of zero points, and in the radio wave environment with less multi-path coverage to the air, the zero points will cause call drop;

[0009] 4. The top gain of the ordinary rod antenna is severely depressed, which will cause over-the-top call drop;

[0010] 5. Support low moving speed;

[0011] 6. Ordinary rod antennas support a narrow range of frequency bands, and one antenna cannot support 4G and 5G frequency bands at the same time, so NSA networking cannot be performed
