Abstract
An antenna includes a radiator, where the radiator includes three parts separated by a gap, an end of a second part proximate to a first part is a first end, and an end of the second part proximate to a third part is a second end, a medium-high frequency feeder, electrically coupled to the radiator at a first coupling point, a low frequency feeder electrically coupled to the radiator, a first ground cable electrically coupled to the radiator at a second coupling point, where an adjustable component for controlling conduction of the first ground cable is disposed on the first ground cable, a length from the second coupling point to an end that is in the first end and the second end and that is further from the first coupling point is a quarter of a wavelength corresponding to a resonance frequency.
