<p>The present invention relates to a multiband antenna system which performs a beam tilt while providing services to multiple bands using a wideband radiating element supporting multiple bands. The multiband antenna system according to the present invention comprises: at least one wideband radiating element; branching filters; and a plurality of phase changers. The at least one wideband radiating element supports multiple bands. Each of the branching filters is connected to the at least one wideband radiating element, and divides signals for respective bands included in the multiple bands. The phase changers are arranged to correspond to the number of the multiple bands, and perform a beam tilt for each band on the divided signals for respective bands. Here, the term′band′as used herein does not mean band for telling transmission from reception, but service bands for service providers.</p> |
