Abstract:
1. A communication device comprising an antenna structure, the antenna structure comprising: a ground element, one edge of the ground element having a notch, and a long edge of the notch being at least two times longer than a short edge of the notch; an antenna element comprising a metal portion disposed at the notch, two ends of the metal portion extending away from each other and being positioned substantially at or around two opposite edges of the notch, one of the two ends of the metal portion coupled to the ground element, and the other of the two ends of the metal portion being a feeding terminal of the antenna element; and a circuit element group comprising at least a capacitive element and an inductive element, the capacitive element and the inductive element arranged in series and coupled to the feeding terminal, the circuit element group causing generation of a first resonant mode in a first operating band of the antenna element, and a length of the metal portion being less than 0.18 wavelength of a lowest frequency in the first operating band of the antenna element.
