Embodiment Construction

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0033] The present invention discloses a beamforming network 1000, such as a five-input and ten-output Butler matrix network. Using the five-beam antenna of the beamforming network, the antenna can form five beams with fixed directions on the horizontal plane. A single fixed-point beam can be formed on the surface. In other words, when electrical signals are input from different input ports, different phase configurations are formed at ten input and output ports, thereby forming five different beam directions.

Abstract

The invention provides a beam forming network and a dual-polarized five-beam antenna. The beam forming network comprises a first network, a second network and a third network connected in sequence, wherein the first network is provided with five signal input ports, and one path of signals can provide two paths of signal inputs for the second network from each signal input port; the second network comprises two three-input four-output matrix network, every two paths of signals provided by the first network are respectively input to the second network from respective one input port of the two matrix networks, and are subjected to coupling and phase modulation of the second network to output eight paths of signals with phase difference; the third network is used for performing power dividing and combination on six of the eight paths of signals output by the second network to form at least ten paths of signals with phase difference. The beam forming network with five input ports and at least ten output ports can be formed, so that different phase configurations are formed at different output ports when signals are input at different input ports, and five different beam directions are formed.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a beamforming network and a dual-polarized five-beam antenna applying the beamforming network. Background technique [0002] At present, technology in the field of mobile communication is developing rapidly, and user traffic continues to blow out. A large number of data services put forward higher requirements for mobile communication capacity. Usually, a mobile communication base station antenna uses a wider beam to cover a sector. When the number of users in the sector increases, problems such as enhanced signal interference and insufficient capacity coverage will be brought about. The multi-beam antenna can be understood as "split" a wider beam into multiple narrower beams, which provides a reliable solution for system capacity expansion at the antenna feeder end. [0003] Using Butler matrix to form multiple beams is one of the main means of multi-beam antenna d...
