Title:

MULTI-BEAM ANTENNA SYSTEM AND PHASE ADJUSTMENT METHOD THEREOF, AND DUAL-POLARIZATION ANTENNA SYSTEM

Document Type and Number:

WIPO Patent Application WO/2015/172667

Kind Code:

A1

Abstract:

A multi-beam antenna system and a phase adjustment method therefor, and a dual-polarization antenna system, which relate to the technical field of communications and achieve a relatively wide coverage range of radiation. The multi-beam antenna system comprises: a one-dimensional multi-beam formation module connected to a radio-frequency port, and a multi-beam formation unit being used for converting radio-frequency signals transmitted via the radio-frequency port into M paths of radio-frequency signals having different phases; a two-dimensional multi-beam formation module, the two-dimensional multi-beam formation module comprising M first power division units, and phase shifters being arranged on P output branches of each power division unit; and M × N radiation units connected to the second multi-beam formation module, the M × N radiation units forming a matrix having N rows and M columns, the M columns of radiation units being connected to the M first power division units respectively, and N radiation units in each column of radio-frequency units being connected to N output branches of one first power division unit respectively, to form a matrix having P rows and M columns with M × P radiation units connected to the output branches provided with the phase shifters.
