Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] see Figure 3 ~ Figure 5 , the present invention provides a broadband dual-polarization radiating unit, which is used to install on a metal reflector to form an antenna. Specifically, the broadband dual-polarization radiating unit 20 includes two pairs of four orthogonally polarized even The poles 2a, 2b, 2c and 2d are used for transmitting or receiving communication signals. The four dipoles 2a, 2b, 2c and 2d are respectively connected to a pair of baluns, wherein each balun includes a straight line segment and an arc segment connected to each other, taking the balun connected to the dipol...

Abstract

The invention is applicable to the technical field of communication and provides a broadband dual-polarized radiating element. The broadband dual-polarized radiating element is used for being installed on a metal reflective plate to form an antenna. The broadband dual-polarized radiating element is characterized in that the radiating element comprises two pairs of orthogonally polarized dipoles which are used for sending or receiving communication signals, each dipole is correspondingly connected with a pair of Baluns, the bottom of each Balun is connected with an annular base, each dipole comprises a first radiating arm and a second radiating arm which are not symmetrically arranged, and two adjacent radiating arms between the dipoles are arranged at the same plane. The invention further provides the antenna which comprises the broadband dual-polarized radiating element. Therefore, the broadband dual-polarized radiating element and the antenna of the broadband dual-polarized radiating element have the advantages of being capable of reducing cross coupling between a high frequency radiating element of a multifrequency antenna and a low frequency radiating element of the multifrequency antenna, simple in structure, convenient to process, high in reliability and good in electrical performance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a broadband dual-polarization radiation unit and an antenna. Background technique [0002] As one of the core devices to realize the coverage of mobile communication network, the base station antenna is an important part of the mobile communication system. In the current environment where 2G and 3G networks coexist and 3G is evolving to LTE, there are more and more requirements for multi-frequency antennas, and the requirements for performance indicators are also getting higher and higher. Compatible with 2G, 3G and LTE2600 frequency band (1710-2690MHz) It has become the trend and inevitable trend of multi-frequency antenna technology development. [0003] In the prior art, multi-frequency antennas compatible with 2G and 3G frequency bands can be divided into two categories according to the relative positions of 2G (low frequency) and 3G (high frequency) radiation units: o...
