Abstract

A mobile device supporting wideband operations includes a first radiation element, a second radiation element, a third radiation element, a fourth radiation element, a fifth radiation element, a sixth radiation element, and a seventh radiation element. The first radiation element has a feeding point. The second radiation element and the third radiation element are coupled to the first radiation element. The first radiation element is coupled through the fourth radiation element to a ground voltage. The fifth radiation element is coupled to the fourth radiation element. The sixth radiation element is coupled to the ground voltage. The sixth radiation element is adjacent to the first radiation element and the third radiation element. The seventh radiation element is coupled to the sixth radiation element. The seventh radiation element extends away from the third radiation element.

First claim

What is claimed is:

1. A mobile device supporting wideband operations, comprising:
a first radiation element, having a feeding point;
a second radiation element, coupled to the first radiation element;
a third radiation element, coupled to the first radiation element, wherein the third radiation element and the second radiation element substantially extend in opposite directions;
a fourth radiation element, wherein the first radiation element is coupled through the fourth radiation element to a ground voltage;
a fifth radiation element, coupled to the fourth radiation element, wherein the fifth radiation element is adjacent to the second radiation element;
a sixth radiation element, coupled to the ground voltage, wherein the sixth radiation element is adjacent to the first radiation element and the third radiation element; and
a seventh radiation element, coupled to the sixth radiation element, wherein the seventh radiation element extends away from the third radiation element;
wherein an antenna structure is formed by the first radiation element, the second radiation element, the third radiation element, the fourth radiation element, the fifth radiation element, the sixth radiation element, and the seventh radiation element;
wherein an angle is formed between the seventh radiation element and the sixth radiation element;
wherein the angle is from 30 to 70 degrees.

2. The mobile device as claimed in claim 1 , wherein a combination of the first radiation element, the second radiation element, and the third radiation element substantially has a T-shape.

3. The mobile device as claimed in claim 1 , wherein the fourth radiation element substantially has a long L-shape.

4. The mobile device as claimed in claim 1 , wherein the fifth radiation element substantially has a short L-shape.

5. The mobile device as claimed in claim 1 , wherein the fifth radiation element is coupled to a central point on the fourth radiation element.

6. The mobile device as claimed in claim 5 , wherein the fourth radiation element comprises a first portion and a second portion with equal lengths, and the central point is positioned between the first portion and the second portion.

7. The mobile device as claimed in claim 1 , wherein the antenna structure covers a first frequency band, a second frequency band, and a third frequency band.

8. The mobile device as claimed in claim 7 , wherein the first frequency band is from 2400 MHz to 2500 MHz, the second frequency band is from 5150 MHz to 5850 MHz, and the third frequency band is from 5925 MHz to 7125 MHz.

9. The mobile device as claimed in claim 7 , wherein a total length of the first radiation element and the second radiation element is substantially equal to 0.25 wavelength of the first frequency band.

10. The mobile device as claimed in claim 7 , wherein a total length of the first radiation element and the third radiation element is substantially equal to 0.25 wavelength of the second frequency band.

11. The mobile device as claimed in claim 7 , wherein a length of the fourth radiation element is substantially equal to 0.5 wavelength of the third frequency band.

12. The mobile device as claimed in claim 7 , wherein a length of the fifth radiation element is substantially equal to 0.25 wavelength of the third frequency band.
