Abstract

An antenna apparatus is provided. The antenna apparatus includes a first section including at least one slit spaced apart from an outer edge of the antenna apparatus by a predetermined distance, a second section distinguished from the first section through the slit, and a feeding module for supplying a current to at least one of the first section and the second section.

First claim

What is claimed is:

1. A portable communication device comprising:
a display forming at least one portion of a front side of the portable communication device;
an antenna forming at least one portion of a rear side of the portable communication device, the at least one portion of the antenna including a first portion having a first size, a second portion having a second size different from the first size, and a slit disposed between the first portion and the second portion, the second portion including a hole formed thereon, and at least one portion of the slit formed in proximity of the hole; and
an electrical component located between the front side and the rear side, at least one portion of the electrical component visible from an outside of the portable communication device via the hole.

2. The portable communication device of claim 1 , wherein the first portion and the second portion form a same planar surface.

3. The portable communication device of claim 1 , wherein at least one portion of the slit is covered with a non-conductive material.

4. The portable communication device of claim 3 , wherein the non-conductive material comprises a dielectric substance having a specified permittivity.

5. The portable communication device of claim 1 , further comprising:
communication circuitry,
wherein the antenna is electrically coupled with the communication circuitry to receive a current from the communication circuitry.

6. The portable communication device of claim 5 , wherein the antenna is electrically coupled with the communication circuitry via a wired connection.

7. The portable communication device of claim 1 , wherein the first portion or the second portion is coupled with a ground of the portable communication device.

8. The portable communication device of claim 1 , wherein the slit is spaced apart from an outer edge of the antenna.

9. The portable communication device of claim 1 , wherein the slit is separated from the hole.

10. An antenna of a portable communication device comprising:
a first radiating portion;
a second radiating portion; and
a slit disposed between the first radiating portion and the second radiating portion,
wherein the second radiating portion includes a hole via which an electrical component of the portable communication device is visible from outside of the portable communication device,
wherein at least one portion of the slit comprises a curved shape, and
wherein the first radiating portion and the second radiating portion form at least one portion of an outer surface of the portable communication device.

11. The antenna of claim 10 , wherein at least one portion of the slit is formed in proximity of the hole.

12. The antenna of claim 10 , further comprising:
another slit on the second portion,
wherein at least one portion of the other slit is formed in proximity of the hole.

13. The antenna of claim 12 , wherein at least part of the slit is in contact with at least part of the other slit.

14. The antenna of claim 12 , wherein the slit and the other slit together form a closed curve.

15. The antenna of claim 12 , wherein the slit is covered with a first non-conductive material and the other slit is covered with a second non-conductive material.

16. A portable communication device comprising:
a display;
short-range communication circuitry; and
a conductive housing forming at least one portion of a rear side of the portable communication device and electrically coupled with the short-range communication circuitry via a wired connection,
wherein the conductive housing comprises:
a first conductive portion,
a second conductive portion, and
a slit disposed between the first conductive portion and the second conductive portion, and

wherein the second conductive portion includes a hole via which at least one portion of an electrical component of the portable communication device is visible from an outside of the portable communication device.

17. The portable communication device of claim 16 , wherein the conductive housing is coupled with the short-range communication circuitry via first matching circuitry.

18. The portable communication device of claim 16 , wherein the first conductive portion or the second conductive portion is coupled with a ground of the portable communication device via second matching circuitry.

19. The portable communication device of claim 16 , wherein at least one portion of the slit is curved.

20. The portable communication device of claim 16 , wherein the electrical component comprises a camera.
