at least one feeding unit;

at least one ground unit connected to the feeding unit; and

a ground member connected to the ground unit,

wherein the feeding unit and the ground unit form a plurality of signal transferring paths.

2. The feeding structure of claim 1, comprising a plurality of ground units.

3. The feeding structure of claim 2, wherein the ground units have mutually different lengths.

4. The feeding structure of claim 2, wherein the ground units have mutually different shapes.

5. The feeding structure of claim 2, wherein the ground units diverge from each other.

6. The feeding structure of claim 1, comprising a plurality of feeding units.

7. The feeding structure of claim 6, wherein the feeding units extend from a feeding point and diverge from each other.

8. The feeding structure of claim 6, wherein the feeding units have mutually different lengths.

9. The feeding structure of claim 6, wherein the feeding units have mutually different shapes.

10. The feeding structure of claim 1, wherein the ground member radiates a signal supplied from the feeding unit.

11. An antenna apparatus comprising:

a feeding structure; and

a radiator to radiate a signal supplied from the feeding structure,

wherein the feeding structure comprises;

at least one feeding unit;

at least one ground unit connected to the feeding unit; and

a ground member connected to the ground unit, and

wherein the feeding unit and the ground unit form a plurality of signal transferring paths.

12. The antenna apparatus of claim 11, wherein the feeding structure comprises a plurality of ground units.

13. The antenna apparatus of claim 12, wherein the ground units have mutually different lengths.

14. The antenna apparatus of claim 12, wherein the ground units have mutually different shapes.
