Abstract
The present invention discloses a multi-beam antenna system, comprising: a one-dimensional multi-beam forming module connected to a radio frequency port, configured to convert a radio frequency signal transmitted by the radio frequency port into M radio frequency signals having different phases; a two-dimensional multi-beam forming module, which includes M first power division units, and a phase shifter is disposed on P output tributaries of each first power division unit; and M×N radiating elements, where the M×N radiating elements form a matrix having N rows and M columns, M columns of radiating elements are respectively connected to the M first power division units, N radiating elements in each column of radiating elements are respectively connected to N output tributaries of one first power division unit, and M×P radiating elements connected to output tributaries disposed with a phase shifter form a matrix having P rows and M columns.
