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

[0026] see figure 1 , figure 2 , the broadband base station antenna radiating unit of the present invention comprises a symmetrical radiation arm 1, a feed sheet 2, a hollow balun support column 3, a hollow feed support column 4, a feed sheet fixing member 15, a plastic base 20 and a feed coaxial cable 23. There are two symmetrical radiation arms 1, and the two symmetrical radiation arms 1 cross each other in a cross-shaped distribution to form a dual-polarized radiator. The two symmetrical radiation arms 1 are rotationally symmetrical with respect to the center of the radiation unit, 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 sheets 2, respectively marked as upper feeding sheet 7 and lower feeding sheet 8, and each feeding sheet 2 is composed of two upright metal sheets and a horizontal metal sheet connecting the...

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 invention relates to the field of wireless communication base station antennas, in particular to a broadband base station antenna radiation unit, and also relates to an antenna array using the radiation unit. Background technique [0002] With the rapid development of mobile communication technology, there are more and more mobile communication systems. The frequency band adopted 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 standards, more and more antennas are installed on base station towers, and the towers in many places have no place for LTE antenna installation. One solution is to use broadband antennas, that is, one antenna can cover frequency bands of multiple communication systems, which can greatly save space on the sky and reduce the difficulty of installation and construction. The key to realizing a broadband antenna is...
