Abstract
An antenna structure for an electronic device includes a first portion, a number of radiating sections, and a number of branch sections. The first portion receives an electric current from a printed circuit board of the electronic device and couples the electric current to the number of radiating sections and the number of branch sections of the antenna structure.
