Abstract

An electronic device is provided. The electronic device includes a first antenna radiator operating in at least one frequency band, and at least one second antenna radiator disposed proximate to the first antenna radiator coupled to at least one radiation pattern of the first antenna radiator, and to operate as a parasitic resonator.

Claims

1. An electronic device comprising:

a first antenna radiator configured to operate in at least one frequency band; and

at least one second antenna radiator electrically coupled to and spaced apart from the first antenna radiator, and configured to operate as a parasitic resonator.

2. The electronic device of claim 1, wherein the second antenna radiator is disposed at a position where at least a portion of the second antenna radiator overlaps the first antenna radiator.

3. The electronic device of claim 1, wherein the second antenna radiator is disposed in parallel so that it does not overlap the first antenna radiator.

4. The electronic device of claim 1, wherein the second antenna radiator is at least one of a metal plate of a predetermined area disposed inside the electronic device, a printed circuit board of flexibility comprising a metal pattern and a conductive tape.

5. The electronic device of claim 1, wherein the second antenna radiator is a metal instrument of the electronic device.

6. The electronic device of claim 5, wherein the metal instrument is at least one of a metal vibrator, a motor, a metal tape, a portion of a shield can, a metal bushing having a predetermined area and a metal bracket.

7. The electronic device of claim 1, wherein the first antenna radiator is disposed in such a way that it is attached on an upper surface of an antenna carrier having a predetermined area and a predetermined height.

8. The electronic device of claim 1, wherein the first antenna radiator is formed in a pattern on a substrate of the electronic device.

9. The electronic device of claim 1, wherein the second antenna radiator is disposed such that it is attached on an inner surface of a case frame of the electronic device.

10. The electronic device of claim 1, wherein the second antenna radiator is insert-molded in a case frame of the electronic device.

11. The electronic device of claim 10, wherein the second antenna radiator is insert-molded such that it is exposed to an inner surface of the case frame or is exposed to an outer surface of the case frame.

12. The electronic device of claim 11, wherein, when exposed to the outer surface of the case frame, the second antenna radiator is utilized as an ornament.

13. The electronic device of claim 1, wherein a radiation pattern of the first antenna radiator that couples with the second antenna radiator is a radiation pattern operating in a Global Positioning System (GPS) band.

14. The electronic device of claim 1, wherein the electronic device is one of a tablet Personal Computer (PC) and a mobile communication terminal.

15. An antenna device comprising:

a first antenna radiator configured to operate in at least one frequency band; and

at least one second antenna radiator disposed proximate to the first antenna radiator coupled to at least one radiation pattern of the first antenna radiator, and configured to operate as a parasitic resonator.

16. An electronic device comprising:

a substrate;

an antenna carrier installed on the substrate or installed to avoid the substrate and having a predetermined height;

a main antenna radiator disposed on an upper surface of the antenna carrier, fed from the substrate, and configured to operate in at least one frequency band; and

at least one auxiliary antenna radiator electrically coupled to and spaced apart from the main antenna radiator, and configured to operate as a parasitic resonator.

17. The electronic device of claim 16, wherein the auxiliary antenna radiator is disposed at a position where at least a portion of the auxiliary antenna radiator overlaps the main antenna radiator.

18. The electronic device of claim 16, wherein the auxiliary antenna radiator is at least one of a metal plate of a predetermined area disposed inside the electronic device, a printed circuit board of flexibility comprising a metal pattern and a conductive tape.

19. The electronic device of claim 16, wherein the auxiliary antenna radiator is a metal instrument of the electronic device.
