Abstract

An antenna includes a ground portion, a radiating element, and an interconnecting element connected to the ground portion and the radiating element. The radiating element includes a first radiating trace including a turning point connected to a first segment and a second segment of the first radiating trace, and a second radiating trace connected to the second segment of the first radiating trace.

Claims

1. An antenna comprising:

a ground portion;

a radiating element comprising;

a first radiating trace including a bended portion connected to a first segment and a second segment of the first radiating trace; and

a second radiating trace connected to the second segment of the first radiating trace; and

an interconnecting element connected to the ground portion and the radiating element.

2. The antenna of claim 1 wherein the interconnecting element includes at least one turning point to subdivide the interconnecting element into a plurality of subsections.

3. The antenna of claim 1 wherein the first segment of the first radiating trace extends away from the grounded portion.

4. The antenna of claim 1 wherein the first segment of the first radiating trace includes a turning point to subdivide the first radiating trace into a plurality of segments.

5. The antenna of claim 1 wherein the interconnecting element is connected to the first radiating trace and the second radiating trace.

6. The antenna of claim 1 wherein a surface of the first segment subtends an angle with a surface of the ground portion.

7. The antenna of claim 1 wherein the first radiating trace further includes a third segment bent from the first segment extending toward the second radiating trace.

8. The antenna of claim 1 wherein a width of the first segment is larger than a width of the second segment.

9. An antenna comprising:

a ground portion;

a radiating element comprising;

a first radiating trace including a first bended portion connected to a first segment and a second segment of the first radiating trace; and

a second radiating trace connected to the second segment of the first radiating trace, the second radiating trace includes a second bended portion connected to a third segment and a fourth segment of the second radiating trace; and

an interconnecting element connected to the ground portion and the radiating element.

10. The antenna of claim 9 wherein the third segment of the second radiating trace is connected to the second segment of the first radiating.

11. The antenna of claim 9 wherein the interconnecting element includes a first turning point to subdivide the interconnecting element into a plurality of segments.

12. The antenna of claim 9 wherein the fourth segment of the second radiating trace extends away from the ground portion.

13. The antenna of claim 9 wherein the fourth segment of the first radiating trace includes a second turning point to subdivide the first radiating trace into a plurality of segments.

14. The antenna of claim 9 wherein the interconnecting element is connected to the first radiating trace and the second radiating trace of the radiating element.

15. The antenna of claim 9 wherein a surface of the first segment subtends an angle with a surface of the ground portion.

16. The antenna of claim 9 wherein a surface of the fourth segment subtends an angle with a surface of the ground portion.

17. The antenna of claim 9 wherein a width of the fourth segment is larger than a width of the third segment.

18. An antenna comprising:

a ground portion;

a radiating element including a bended portion connected to a first segment and a second segment of the radiating element; and

an interconnecting element connected to the ground portion and the second segment of the radiating element;

wherein the first segment extends in a direction substantially parallel to the second segment.

19. The antenna of claim 18 wherein the first segment of the radiating element extends away from the ground portion.

20. The antenna of claim 18 wherein a surface of the first segment subtends an angle with a surface of the ground portion.

21. The antenna of claim 18 wherein a width of the first segment is larger than a width of the second segment.
