Abstract
An antenna structure includes a radiating portion and a coupling portion. The radiating portion is electrically connected to a feed point for feeding current. The coupling portion is electrically connected to a ground point to be grounded. The coupling portion is spaced apart from the radiating portion. The radiating portion excites a first resonant mode for generating radiation signals in a first frequency band. The current flowing through the radiating portion is coupled to the coupling portion, and the coupling portion excites a second resonant mode and a third resonant mode for generating radiation signals in a second frequency band and a third frequency band. Frequencies of the first frequency band are higher than frequencies of the second frequency band. Frequencies of the third frequency band are higher than frequencies of the first frequency band.
