Antenna oscillator baseThe quasi-directions are perpendicular to the two orthogonal faces of the L-shape, respectively. Is installed on two walls or other corners of buildings.

Description

L-shaped antenna

This application is a divisional application entitled "L-shaped antenna Module" filed as original application No. 2019206393267

Technical Field

The invention relates to a mobile communication base station antenna, in particular to a base station antenna module installed on a building.

Background

As is known to all, the base station antenna installed on the roof is often too high in height, and shadow effect is easily generated due to the blocking of the building body; if the base station antenna is installed on a wall, the antenna can only cover the direction of the wall, and if a plurality of directions are covered, a plurality of antennas must be installed on a multi-surface wall, so that the construction difficulty is increased, and the antenna cost is increased.

Disclosure of Invention

The purpose of the invention is: designing an L-shaped antenna, including 5G AAU products, or other devices incorporating an antenna, typically 90⁰The corner is arranged at the corner position between two adjacent walls of the building, so that two sides of the L-shaped antenna module can respectively cover the directions of the two walls, and the highest angle can reach or slightly exceed 270 DEG⁰The coverage of (2).

One of the technical solutions of the present invention is to design the antenna in an L-shape, the signal plane of the antenna is two external sides of an L-shape right angle, and the horizontal direction of the signal coverage range can slightly exceed 270⁰. The wall corner fixing device is suitable for being installed at the transverse most protruding part of the whole wall of two walls at the corner. Mounted on a wall or other structure, the antenna being L-shaped in cross-section and having an outer L-plane, i.e. 270, with reference to the direction of coverage⁰The inner L surface is the vertical orthogonal two surfaces of the wall mounting surface. The reference directions of the antenna elements are respectively vertical to two orthogonal surfaces of the L shape. Is installed on two walls or other corners of buildings.

The second technical solution of the invention is as follows: the housing of the base station on the wall is designed into L shape, the antenna signal surface is two end vertical surfaces of L shape, the total coverage range is slightly over 270 in horizontal direction⁰And correspondingly arranging the devices in the antenna module. Is suitable for being arranged at the most convex part of two adjacent walls at the corner of the wall, which is not the whole wall, and has 90⁰Wall corner with inward sunken corner

The invention has the advantages that: the coverage is large, and the coverage cost is reduced.

Drawings

Fig. 1 is an overall schematic diagram of an L-shaped antenna;

FIG. 2 is a schematic view of an L-shaped antenna arrangement mounted at a corner;

fig. 3 is a schematic view of the installation of the second L-shaped antenna scheme.

The specific implementation mode is as follows: the following is combined withThe figure further illustrates the solution according to the invention. As shown in the figure, the antenna has an L-shaped cross section, 1 is a mounting base plate, and 2 is an antenna housing. The orthogonal two surfaces of the inner L surface use metal plates as bottom plates, the outer part is customized to be a radome which is made of electromagnetic wave-transmitting materials, antenna units are respectively arranged at the two surfaces and the included angle of the bottom plates in the module, 1 pair, 2 pairs or multiple pairs of antenna units can be arranged, multiple pairs of antenna units can be arranged according to the upper layer and the lower layer, the total coverage range of the antenna units in the horizontal direction slightly exceeds 270⁰. And installing other units of the antenna module on the bottom plate and well performing connection debugging. During installation, the L-shaped surface right angle in the bottom plate of the antenna module is attached to the outer corner of the wall body and fixed by bolts. In the second scheme, as shown in fig. 3, metal plates are used as bottom plates on two orthogonal surfaces of the outer L surface, two antenna unit brackets are mounted on the inner sides of two end surfaces of the L-shaped right-angle bottom plate, multiple antenna units can be mounted by layering up and down, and the horizontal direction of the coverage range of the antenna units slightly exceeds 270⁰And installing other units of the antenna module on the bottom plate and well performing connection debugging. And the outer part is made into an antenna housing made of an electromagnetic wave transmitting material. When the installation is carried out, the outer right angle of the outer L surface is attached to the inner right angle of the wall body, and the bottom plate is fixed on the wall through screws.
