Multi-band antenna system

Abstract

The present invention relates to a multiband antenna system and, more particularly, to a multiband antenna system which performs beam tilt while servicing a multiband with a broadband radiating element supporting a multiband. The multiband antenna system according to the present invention comprises: at least one broadband radiating element; a branching filter; and a plurality of phase shifters. The at least one broadband radiating element supports a multiband. The branching filter is connected to each of the at least one broadband radiating element and branches signals per band included in the multiband. The plurality of phase shifters are provided to correspond to the number of the multibands and perform beam tilt for the signals branched per band in accordance with each band. Here, the band means not a band for dividing receipt and transmission in a particular band, but a service band per service provider.
