Abstract

A feeding network, an antenna, an antenna system, a base station, and a beam forming method. The antenna includes an array antenna, a feeding network, and an antenna port. The array antenna includes a plurality of radiating elements. Each output of each feeding network is connected to at least one radiating element in the array antenna. Each input of each feeding network is connected to the antenna port. Each feeding network has one input and two outputs, and one of the two outputs includes a phase shifter. The phase shifter has a first operating state to increase the coverage space of beam forming.
