Vector synthesis base station antenna unit

Abstract

The invention discloses a vector synthesis base station antenna unit. A feeding structure is horizontally fixed above a reflection plate through support columns. The upper surface of the feeding structure is vertically equipped with a main radiator. The main radiator is a rectangular structure formed by four conductive plates, and the upper and lower ends of the rectangular structure are opened. Two adjacent conductive plates have a gap. The feeding structure comprises a dielectric plate. The upper surface of the dielectric plate and the lower opening of the main radiator are respectively provided a patch. The two diagonal lines of the patch are respectively provided with a seam. The lower surface of the dielectric plate is printed by a first feed line and a second feed line. The first feed line surrounds the seam of one diagonal line; and the second feed line surrounds the seam of the other diagonal line. The reflection plate is provided with a through hole for allowing radio frequency cables to pass. The inner cores of the two radio frequency cables are welded with the first feed line and the second feed line respectively; and the outer cores of the two radio frequency cables arewelded with the patches respectively. The vector synthesis base station antenna unit is small in size, wide in frequency band and stable in radiation property, and can meet market requirements.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a vector synthesis base station antenna unit, in particular to a dual-polarization base station antenna unit with small volume, simple structure, convenient processing and excellent performance, which can be used for mobile communication base station antenna arrays. Background technique [0002] The base station refers to the radio transceiver station that transmits information between the mobile communication switching center and the mobile terminal in a certain radio coverage area. Among them, the antenna, as one of the most important components in the base station, is mainly responsible for the communication equipment. Electrical signals and space radiated electromagnetic waves are converted. Base station antenna design is very important in base station applications. With the development of 2G / 3G / 4G / 5G wireless communication systems, base station antennas also need...
