1. A mobile device, comprising:
- a ground plane;
a first radiation branch; and
a second radiation branch, coupled to the ground plane, and disposed adjacent to the first radiation branch;
wherein an antenna structure is formed by the first radiation branch and the second radiation branch, the first radiation branch is fed from a signal source, and the second radiation branch is excited by the first radiation branch through coupling therebetween;
wherein the mobile device further comprises;
a metal back cover, disposed opposite to the ground plane; and
one or more shorting pins, wherein the metal back cover is coupled through the shorting pins to the ground plane,wherein the metal back cover consists of two portions which are completely separate from each other,wherein a first opening and a second opening are respectively formed between the two portions of the metal back cover, andwherein each of the first opening and the second opening has a triangular shape, a square shape, or a trapezoidal shape.

Abstract
A mobile device includes a ground plane, a first radiation branch, and a second radiation branch. The second radiation branch is coupled to the ground plane, and is disposed adjacent to the first radiation branch. An antenna structure is formed by the first radiation branch and the second radiation branch. The first radiation branch is fed from a signal source. The second radiation branch is excited by the first radiation branch through coupling therebetween.

21. A method for manufacturing a mobile device, comprising the steps of:
-
providing a ground plane, a first radiation branch, and a second radiation branch; coupling the second radiation branch to the ground plane, wherein the second radiation branch is disposed adjacent to the first radiation branch; using the first radiation branch and the second radiation branch to form an antenna structure, wherein the first radiation branch is fed from a signal source, and the second radiation branch is excited by the first radiation branch through coupling therebetween; providing a metal back cover, wherein the metal back cover is disposed opposite to the ground plane; and coupling the metal back cover through one or more shorted-circuit elements to the ground plane, wherein the metal back cover consists of two portions which are completely separate from each other, wherein a first opening and a second opening are respectively formed between the two portions of the metal back cover, and wherein each of the first opening and the second opening has a triangular shape, a square shape, or a trapezoidal shape. - View Dependent Claims (22, 23)
