Abstract

An antenna (10) is provided. The antenna (10) with coupling feeding, printed on a substrate (30) for transceiving electromagnetic signals. The antenna includes a radiator (12), a feeding portion (14), and a grounded portion (16). The radiator is for the transceiving electromagnetic signals. The feeding portion defines a gap with the radiator for coupling feeding the electromagnetic signals to the radiator via the gap. The grounded portion is disposed adjacent to the feeding portion.

Claims

1. An antenna with coupling feeding, printed on a substrate for transceiving electromagnetic signals, comprising:

a radiator, in a mazelike shape, for transceiving electromagnetic signals;

a feeding portion, defining a gap with the radiator, for coupling feeding the electromagnetic signals to the radiator via the gap; and

a grounded portion, disposed adjacent to the feeding portion.

2. The antenna as recited in claim 1, wherein the antenna is a monopole antenna.

3. The antenna as recited in claim 2, wherein the radiator of the monopole antenna is in a helical shape.

4. The antenna as recited in claim 2, wherein the feeding portion comprises a coupling portion, which is disposed parallel to the radiator and defines a gap therewith.

5. The antenna as recited in claim 4, wherein the feeding portion further comprises a transmission portion electronically connected to the coupling portion.

6. The antenna as recited in claim 5, wherein the transmission portion comprises a first transmission line electronically connected to the coupling portion, and a second transmission line electronically connected to the coupling portion and disposed parallel to the first transmission line.

7. The antenna as recited in claim 6, wherein the transmission portion further comprises a third transmission line electronically connected to the first transmission line and the second transmission line, and a fourth transmission line electronically connected to the third transmission line and disposed between the grounded portion.

8. The antenna as recited in claim 1, wherein the antenna is a planar inverted F antenna.

9. The antenna as recited in claim 1, wherein the radiator comprises a first radiating portion electronically connected to the grounded portion.

10. The antenna as recited in claim 9, wherein the radiator further comprises a second radiating portion, and a connecting portion electronically connected to first radiating portion and the second radiating portion.

11. The antenna as recited in claim 10, wherein the second radiating portion is in a comblike shape, a W shape, an S shape, or a U shape.

12. The antenna as recited in claim 11, wherein the connecting portion is electronically connected to the first radiating portion and the second radiating portion and defines the comblike shape, the W shape, the S shape, or the U shape.

13. The antenna as recited in claim 10, wherein the feeding portion comprises a coupling portion, is parallel to the connection portion and defines a gap therewith.

14. The antenna as recited in claim 13, wherein the feeding portion further comprises a transmission portion connected to the coupling portion.

15. An antenna with coupling feeding, printed on a substrate for transceiving electromagnetic signals, comprising:

a radiator, comprising a first radiating portion, a connecting portion, and a second radiating portion, wherein the first radiating portion, the connecting portion, and the second radiating portion are connected end to end in a helical shape or mazelike shape;

a feeding portion, defines a gap with the connecting portion, for coupling feeding the electromagnetic signals to the radiator via the gap; and

a grounded portion, disposed adjacent to the feeding portion.
