1. A beamforming apparatus comprising:
a beamforming module comprising a beam port, the beam port configured to provide first electrical signals;
an antenna array comprising a plurality of antenna ports; and
a feeding network disposed between and coupling the beam port and the plurality of antenna ports, the feeding network configured to shunt the first electrical signals provided by the beam port to the plurality of antenna ports, wherein:
second electrical signals received at the antenna ports are used to control shapes of beams formed by the antenna array;
amplitudes of the second electrical signals shunted to the plurality of antenna ports and an operating frequency of the antenna array meet a first correspondence;
a phase difference between two of the second electrical signals shunted to two different antenna ports and the operating frequency meet a second correspondence;
the first correspondence comprises that the amplitudes decrease as the operating frequency increases; and
the second correspondence comprises that the phase difference increases as the operating frequency increases.
