Embodiment 1

[0030] In this embodiment, the antenna array includes at least one first radiating unit (unnumbered, the same below) and at least one second radiating unit (unnumbered, the same below), and the first and second radiating units are double The polar oscillators each include two pairs of dipoles with orthogonal polarizations. In the antenna array, one first radiating unit and one second radiating unit are arranged side by side on the antenna reflector in a one-to-one correspondence, so as to construct two rows of antennas on the left and right.

[0031] like figure 1 shown in figure 1 In , the solid line represents the feeder of the antennas in the left column, and the dotted line represents the feeder of the antennas in the right column. Taking a first radiating unit and a second radiating unit arranged in parallel as an example, the first radiating unit (that is, a dual-polarized vibrator on the left) includes two pairs of dipoles 101, 102, 103, 104 with orthogonal polarizati...

Embodiment 2

[0038] The antenna array of this embodiment is similar to Embodiment 1, the difference lies in:

[0039] see figure 2 , in this embodiment, the dipole 101 and the dipole 201 are arranged in parallel as the positive polarization of the left column antenna. Similarly, dipole 104 and dipole 204 are connected in parallel as the negative polarization of the left antenna, and dipole 102 and dipole 202 are connected in parallel as the right polarization of the antenna. Dipole 103 and dipole The poles 203 are connected in parallel in an array as the negative polarization of the right column antenna.

Embodiment 3

[0041] The antenna array of this embodiment is similar to Embodiment 1, the difference lies in:

[0042] see image 3 , in this embodiment, the first and second radiating elements of the left and right antenna arrays are vertically staggered, that is, the line connecting the centers of the two dual-polarized oscillators corresponding to the array is an oblique line.

Abstract

The invention provides an antenna array, which comprises at least one first radiating element and at least one second radiating element, wherein each second radiating element is vertical to the axis of an array in which the first radiating element is located; each first radiating element comprises two pairs of orthogonally polarized dipoles; each second radiating element comprises at least one pair of orthogonally polarized dipoles; and at least one dipole of each first radiating element is connected with one same polarized dipole in each second radiating element through a feeder for shunt feeding through a feed network. A horizontal beam of an antenna can be narrowed to a certain extent by increasing the space between two same polarized dipoles for shunt feeding, so that the problem that the horizontal beam is widened when the antenna size is reduced is solved; the gain and the front-to-rear ratio of the antenna are improved; and miniaturization of the antenna is facilitated. In addition, the invention further relates to the antenna of using the antenna array. The antenna has relatively high gain and front-to-rear ratio and miniaturization is achieved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication antennas, in particular, the present invention relates to an antenna array and an antenna using the antenna array. Background technique [0002] With the gradual acceleration of 4G mobile communication network deployment, in order to realize the improvement of system capacity, the current general implementation means is MIMO (Multiple-Input Multiple-Output, Multiple-Input Multiple-Output) system. Among them, the base station antenna technical solution is to arrange two antenna arrays side by side. Based on the existing technology, in order to ensure the radiation performance of the antennas, the distance between the antenna arrays arranged side by side is relatively large. The intuitive performance is that the antenna width is huge and occupies a large installation space. [0003] However, with the limitation of station building space and the increasing difficulty of property ...
