Abstract
A beamforming method and apparatus are provided. A beamforming apparatus according to one embodiment comprises a beamforming module comprising a beam port configured to provide electrical signals; an antenna array comprising a plurality of antenna ports; and a feeding network disposed between and coupling the beam port and the antenna ports. The feeding network is configured to shunt the electrical signals provided by the beam port to the plurality of antenna ports, the electrical signals received at the antenna ports being used to control shapes of beams formed by the antenna array. An amplitude of an electrical signal shunted to an antenna port and an operating frequency of the antenna array meet a first correspondence. A phase difference between electrical signals shunted to two different antenna ports and the operating frequency meet a second correspondence.
