Problems solved by technology

The dual-polarized radiating unit can reduce the number of antennas on the site, reduce the size and weight of the antenna, but the pattern of the two polarization directions of the dual-polarized antenna is often not consistent, resulting in inconsistent coverage of the two channels, thus affecting the site coverage effect

Embodiment Construction

[0025] With reference to the accompanying drawings and embodiments, the following provides a detailed description of the technical solutions of the present invention.

[0026] see figure 1 , figure 2 , the broadband base station antenna radiation unit of the present invention includes a symmetrical radiating arm 1, a feeding piece 2, a hollow balun support column 3, a hollow feeding support column 4, a feeding piece fixing member 15, a plastic base 20 and a feeding coaxial cable 23. There are two symmetrical radiating arms 1, and the two symmetrical radiating arms 1 cross each other and are distributed in a cross shape, forming a dual-polarized radiator. The two symmetrical radiating arms 1 are rotationally symmetric with respect to the center of the radiating element, so the radiators are the same for the two polarization directions, and this arrangement can enhance the consistency between the two polarizations.

[0027] see Figure 4 to Figure 6 , there are two feeding p...

Abstract

Provided are a broadband base station antenna radiating element and an array antenna. The radiating element comprises symmetrical radiating arms, feed pieces, hollow Balun supporting columns, hollow feed supporting columns, feed openings, feed piece fixing parts and feed coaxial cables, wherein two symmetrical radiating arms are intersected and distributed in a cross-shaped mode and symmetrically rotate relative to the center of the radiating element, one arm of the symmetrical radiating arms is connected with the hollow feed supporting columns, and the other arm is connected with the hollow Balun supporting columns. The number of the feed pieces is two, an auxiliary upright metal sheet of each feed piece is fixed in one hollow Balun supporting column, a main upright metal sheet of each feed piece is fixed in one hollow feed supporting column, the feed openings are arranged at the bottoms of the hollow feed supporting columns, outer conductors of the feed coaxial cables are fixed on the feed openings, and inner conductors of the feed coaxial cables are connected with the auxiliary upright metal sheet of one feed piece.

Description

technical field [0001] The present invention relates to the field of wireless communication base station antennas, in particular to a broadband base station antenna radiating unit, and the present invention also relates to an antenna array using the radiating unit. Background technique [0002] With the rapid development of mobile communication technologies, there are more and more mobile communication systems, and the frequency band used by LTE (Long Term Evolution, Long Term Evolution) developed in recent years has reached 2500-2690 MHz. On the other hand, with the increase of mobile communication systems, more and more antennas are installed on base station towers, and towers in many places have no space for LTE antenna installation. One solution is to use a broadband antenna, that is, a pair of antennas can cover the frequency bands of multiple communication standards, which can greatly save the sky space and reduce the difficulty of installation and construction. The k...
