In addition, generally, the excitation unit 23 is located at a relatively short distance from the radiator 22, so as to facilitate signal transmission between the two through coupling and feeding. For example, the distance between the excitation unit 23 and the radiator 22 can be controlled at a position less than 2mm, 1mm or 0.1mm, etc., the smaller the distance between the excitation unit 23 and the radiator 22, the smaller the coupling between the two powerful.
