Problems solved by technology

[0006] The multi-beam antenna system in the prior art can only use a 4*4 Butler matrix to form multi-beams, and cannot use other types of Butler matrices to form multi-beams
Moreover, since the radio frequency signals output by the 4+M output terminals of the power secondary distribution circuit have a phase difference, at least one of the multi-beams formed by the 4+M multi-beam antenna units has no beam pointing directly forward
