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. An antenna apparatus comprising:
a first section including at least one slit spaced apart from an outer edge of the antenna apparatus by a specified distance;
a second section distinguished from the first section through the at least one slit; and
a feeding module for supplying a current to at least one of the first section and the second section,
wherein a hole is formed in the second section, and
wherein at least a portion of at least one component included in an electronic device including the antenna apparatus is exposed to the outside of the electronic device through the hole.

2. The antenna apparatus of claim 1 ,
wherein the first section and the second section form at least a portion of a cover of the electronic device, and
wherein the at least a portion of the cover includes a conductive material.

3. The apparatus of claim 1 , wherein the at least one slit surrounds at least a part of the outer edge of the second section.

4. The antenna apparatus of claim 1 , wherein the at least one slit is at least partially filled with an insulation member.

5. The antenna apparatus of claim 4 , wherein the insulation member is determined from among a plurality of insulation members differing in permittivity based on a size of at least one of the first section, the second section, and the at least one slit.

6. The antenna apparatus of claim 1 , wherein the feeding module is connected to the second section.

7. The antenna apparatus of claim 1 , further comprising a ground connection module for connecting at least one of the first section and the second section to a ground.

8. The antenna apparatus of claim 7 , wherein the ground connection module comprises:
a matching circuit,
wherein at least one of the first section and the second section is grounded through the matching circuit.

9. An electronic device comprising:
a circuit board; and
an antenna to which electric power is fed through the circuit board,
wherein the antenna comprises:
a first section comprising a slit spaced apart from an outer edge of the electronic device by a specified 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 from the circuit board, wherein at least a portion of the first section is formed of a conductive material, and
wherein at least a portion of at least one component included in the electronic device is exposed to the outside of the electronic device through a hole formed in the second section.

10. The electronic device of claim 9 , further comprising:
a ground connection module for connecting at least one of the first section and the second section to a ground.

11. The electronic device of claim 10 , wherein the ground connection module comprises:
a ground pin disposed in the first section or the second section;
a ground connection wire connecting the ground pin to a ground layer of the circuit board; and
a matching circuit disposed between the ground connection wire and the ground layer.

12. The electronic device of claim 9 , wherein the at least one slit comprises a first slit and a second slit, and the first slit and the second slit surround at least a portion of an outer edge of the second section.

13. The electronic device of claim 9 , wherein the second section is a conductive component included in at least a portion of a component forming the electronic device.

14. The electronic device of claim 13 , wherein the conductive component surrounds at least a portion of an outer edge of the component and is exposed to the outside of the electronic device.

15. The electronic device of claim 9 , wherein the first section and the second section form at least a portion of a case formed on one surface of the electronic device.

16. The electronic device of claim 9 , wherein the circuit board comprises a current supply module, and
the feeding module comprises:
a feeding pin disposed in the second section; and
a feeding wire connecting the feeding pin and the current supply module.

17. The electronic device of claim 9 , wherein at least a portion of the at least one slit is filled with an insulation member.

18. An electronic device comprising:
a circuit board comprising a ground layer;
a cover comprising a conductive material in at least one area and covering at least a portion of the circuit board; and
an antenna apparatus configured by at least an area of the cover,
wherein the antenna apparatus comprises:
a first area at least a portion of which is surrounded by at least one slit spaced apart from an outer edge of the cover by a predetermined distance,
a second area distinguished from the first area by the at least one slit,
a feeding wire for supplying a current to the first area, and
a ground connection wire for connecting at least one of the first area and the second area to the ground layer, and

wherein a hole is formed in the first area, and
wherein at least a portion of at least one component included in the electronic device is exposed to the outside of the electronic device through the hole.
