Abstract: An antenna includes a first element, a second element, and a reactance-adjustable component. The first element receives an excitation current through an electrical connection to an antenna feeder, and the second element generates an induced current through electromagnetic induction of the first element. The reactance-adjustable component is disposed at an end of the first element close to a reference plane, and/or the reactance-adjustable component is disposed at an end of the second element close to a reference plane. The reference plane uses a connection point between the first element and the antenna feeder as an origin point and is perpendicular to an axial direction of the first element. The reactance-adjustable component has an adjustable reactance value and is configured to adjust a phase difference between an excitation current and an induced current, where the phase difference has an association relationship with a target angle of radiation of the antenna.
