Claim Text:
1. A manufacturing method for producing an antenna and a mobile device, comprising the steps of: providing a substrate; providing a ground element comprising a ground branch, wherein an edge of the ground element has a notch extending into an interior of the ground element to form a slot region, and the ground branch partially surrounds the slot region; disposing a radiating branch inside the slot region; coupling the radiating branch to the ground branch of the ground element such that the ground branch and the radiating branch form an antenna structure; and providing a parallel feeding element, wherein a signal source is coupled through the parallel feeding element to a feeding point on the ground branch and to a first terminal of the radiating branch, respectively, wherein the ground branch of the antenna structure is excited to form a first frequency band, and the radiating branch of the antenna structure is excited to form a second frequency band, wherein a first current path from a grounded end of the ground branch through the feeding point to an open end of the ground branch is excited to generate a part of the first frequency band, and a second current path from the feeding point to the open end of the ground branch is excited to generate another part of the first frequency band, wherein the ground element is a conductive housing of the mobile device, and the substrate and the radiating branch are disposed in the conductive housing, and wherein the manufacturing method further comprises: providing a transparent nonconductive structure which is partially embedded into the notch of the ground element so as to separate the ground element from an open end of the ground branch; and disposing an LED (Light Emitting Diode) on the substrate, wherein the LED generates light through the transparent nonconductive structure.
