Embodiment Construction

[0034] Attached below Figure 1-15 The dual-polarized array antenna and its radiation unit of each embodiment of the present invention will be further described.

[0035] A dual-polarized array antenna, on which a reflector 30 is sequentially arranged with several radiating elements, where the number may be odd or even. Each radiating unit is a dual-polarized radiating unit, which has two pairs of radiating oscillators installed orthogonally, and each pair of radiating oscillators is used to radiate a polarized signal.

[0036] Such as figure 1 and 2 As shown, the structure and shape of at least one radiating unit are as follows:

[0037] The radiating unit is defined as the first radiating unit 10, and one pair of radiating oscillators of the radiating unit 10 is used to radiate the signal of the first polarization. Taking the ±45° dual-polarized radiating unit as an example, it can be radiated at +45° The polarized signal defines the pair of radiating oscillators as the ...

Abstract

The invention provides a dual polarization array antenna which comprises a number of radiation units arranged on the reflecting board in an array. Each radiation unit has two pairs of radiation oscillators which are in orthogonal polarization arrangement. At least one radiation unit is used as a first radiation unit, and at least one radiation unit is used as a second radiation unit. A first pair of radiation oscillators of the first radiation unit is used for radiating a first polarization signal, and the second pair of radiation oscillators is used for radiating a second polarization signal. A first pair of radiation oscillators of the second radiation unit is used for radiating the second polarization signal, and the second pair of radiation oscillators is used for radiating the first polarization signal. Based on the vertical direction of the reflecting board, the first pairs of radiation oscillators of the first radiation unit and the second radiation unit are designed to be higher than the second pairs of radiation oscillators. According to the invention, the consistency of the radiation performance between two polarizations of the array antenna can be greatly improved, and the polarization isolation of the array antenna is improved.

Description

technical field [0001] The invention relates to the field of mobile communication antennas, in particular to a dual-polarization array antenna and a radiation unit thereof. Background technique [0002] A typical feature of a common dual-polarization radiation unit is that the structural size and shape of the two polarized radiation oscillators are consistent, and each radiation oscillator is arranged on the same plane, that is, the two polarized radiation oscillators rotate 90° and overlap. Although this design can improve the consistency of the radiation performance of the two polarizations to a certain extent, in order to avoid feed interference, the feed ports of the two polarizations can only be set on different planes. It is impossible to arrange the feed ports on the same plane. The array antenna formed by the consistency of the above-mentioned radiating elements will inevitably cause the radiation of the two polarizations to There are certain differences in perform...
