Abstract

Disclosed is a digital multi-beam antenna which mainly includes upper and lower antenna arrays, uplink and downlink digital channels, a digital multi-beam formation multiplier processor and a communication signal processor. An output end of the uplink digital channel is connected to an input end of a radio frequency module. An output end of the radio frequency module is connected to an input end of an anti-interference intermediate frequency module. An output end of the anti-interference intermediate frequency module is connected to an input end of an uplink. An output end of the uplink is connected to the digital multi-beam formation multiplier processor. The digital multi-beam formation multiplier processor outputs to an input end of an downlink and the downlink inputs to the downlink digital channel. An input end of the lower antenna array is connected to the downlink digital channel. Through setting of the radio frequency module, the digital multi-beam antenna is enabled to have frequency conversion, amplification, filtering and intermediate frequency output functions and is excellent in channel uniformity, higher in anti-interference capability, and more suitable for use demands of modern society and people; and the digital multi-beam antenna is also comparatively low in manufacturing cost and suitable for mass production.

Description

technical field [0001] The invention relates to antenna structure technology, in particular to a digital multi-beam antenna. Background technique [0002] According to the structural form, multi-beam antennas can be roughly divided into two basic forms: reflective and direct-beam; according to the beamforming method, it can be attributed to analog multi-beam forming and digital multi-beam forming: each form of antenna can work in both receiving and transmitting. mode. [0003] The direct-beam multi-beam antenna uses a beamformer in the form of a power combining distribution network, etc., by controlling the phase of the antenna unit, in different directions, the electromagnetic wave satisfies the same "spatial phase difference" and "in-array phase difference", thereby simultaneously forming Multiple beams in different directions. Direct-beam multibeam antennas can be used analog or digitally to form a large number of wide-angle scanning beams at RF, IF, or baseband...
