Embodiment Construction

[0025] A base station antenna radiating unit with a low-profile polarization-separated design designed by the present invention considers the design of the polarization separation to make the structure of the element simple, fast to assemble and reduce the coupling interference between the two polarizations. Lun's design, so the profile of the radiation unit is very low, which provides a favorable technical basis for solving the miniaturization of existing base station antennas.

[0026] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] The novel base station antenna radiating unit of the present invention includes a feeding balun, a radiating surface and a coaxial cable. The radiation surface includes two separate dipoles, which are respectively placed along different polarization directions. The present invention is designed to place the feed welding points along the horizon...

Abstract

The invention relates to a low-profile base station antenna radiation unit and an antenna. The low-profile base station antenna radiation unit is characterized by comprising a radiation surface, a radiation arm, a feeding probe, feeding Baluns and a coaxial cable, wherein the radiation surface comprises two dipoles, the two dipoles are separated and are placed respectively along different polarization directions, two paths of polarization with +45 degrees and -45 degrees are formed along directions of +45 degrees and -45 degrees, the radiation arm is arranged on the radiation surface and employs a microstrip mode, coupling feeding is achieved on each dipole by the feeding probe, each dipole is provided with each feeding Balun, a lower end of the coaxial cable is connected with bottom parts of the feeding Baluns, and an upper end of the coaxial cable and upper ends of the feeding Baluns are welded at a feeding position of the radiation surface. By employing a polarization technology, an unbalanced feeding line such as a strong-coupling microstrip and a coaxial line is supported to feed, thus, the radiation unit has the characteristics of wide band, high gain, low loss, low profile and high anti-interference capability and has important market value, and the demand of miniature design of the base station antenna can be satisfied.

Description

technical field [0001] The invention relates to the technical field of antenna radiation units, in particular to a low-profile base station antenna radiation unit and a corresponding antenna. Background technique [0002] The base station is an important part of mobile communication, and the antenna is an important component of the base station, which directly determines the quality of mobile communication network coverage and signal transmission. As one of the key components of the base station antenna, the radiation unit plays a vital role in the quality of the entire mobile communication network. [0003] In the prior art, the radiating unit of the antenna is generally realized by welding the feed sheet process to feed the balun to the vibrator, and the two polarizations of ±45° are integrated into one whole, which brings complex structure and difficult production of the radiating unit Disadvantages of large size, high cost, and large interference between polarizations. ...
