a cover configured to cover at least one surface of the mobile device, the cover including a second metal material, and the cover and at least a portion of the frame configured to form a signal path such that the cover and the at least the portion of the frame are configured to operate as a second antenna for a second wireless communication.

2. The housing of claim 1 , wherein a frequency band used in the first wireless communication is different from a frequency band used in the second wireless communication.

3. The housing of claim 1 , wherein the first wireless communication is a non-near field communication, and the second wireless communication is a near field communication.

4. A housing of a mobile device comprising:
a frame defining a perimeter of the mobile device, the frame including a first metal material and configured to operate as a first antenna for a first wireless communication, the frame including,
a metal structure defining the perimeter of the mobile device, and having a slit defined therein at one side of the mobile device,
an insulator in the slit, and
a first terminal coupled to the metal structure and being adjacent to the insulator, and

a cover configured to cover at least one surface of the mobile device, the cover including a second metal material, and the cover and at least a portion of the frame configured to operate as a second antenna for a second wireless communication, the cover including,
a metal region,
an insulating region being adjacent to the one side of the mobile device, and
a second terminal on the metal region, the second terminal being adjacent to the insulating region such that the insulating region is between the first terminal and the second terminal.

5. The housing of claim 4 , wherein the housing is configured to perform the second wireless communication by using a signal path formed around the insulating region.

6. The housing of claim 5 , wherein the signal path is provided along the first terminal, a portion of the metal structure, a portion of the metal region and the second terminal.

7. The housing of claim 5 , where the cover further includes a magnetic sheet on at least a portion of the signal path.

8. The housing of claim 5 , wherein the frame further includes:
at least one inductor or at least one low pass filter at the signal path.

9. A housing of a mobile device, comprising:
a frame defining a perimeter of the mobile device, the frame including a first metal material and configured to operate as a first antenna for a first wireless communication, the frame including,
a metal structure defining the perimeter of the mobile device, the metal structure being divided into first through third regions by first and second slits, the first slit between the first region and the second region, and the second slit between the second region and the third region,
a first inductor at the first slit, the first inductor having a first end and a second end, the second end coupled to the second region of the metal structure,
a second inductor at the second slit, the second inductor having a third end and a fourth end, the third end coupled to the second region of the metal structure, and the fourth end coupled to the third region of the metal structure, and
a first terminal coupled to the first end of the first inductor; and

a cover configured to cover at least one surface of the mobile device, the cover including a second metal material, and the cover and at least a portion of the frame configured to operate as a second antenna for a second wireless communication.

10. The housing of claim 9 , wherein the cover includes,
a metal region,
an insulating region adjacent to an one side of the mobile device, and
a second terminal on the metal region, the second terminal being adjacent to the insulating region such that the insulating region is between the first terminal and the second terminal.

11. The housing of claim 10 , wherein the housing is configured to perform the second wireless communication by using a signal path provided along the first terminal, the first inductor, the second region of the metal structure, the second inductor, the third region of the metal structure, a portion of the metal region and the second terminal.

12. A housing of a mobile device, comprising:
a frame defining a perimeter of the mobile device, the frame including a first metal material and configured to operate as a first antenna for a first wireless communication, the frame including,
a metal structure defining the perimeter of the mobile device, the metal structure being divided into first through third regions by first and second slits, the first slit between the first region and the second region, and the second slit between the second region and the third region,
a first low pass filter at the first slit, the first low pass filter having a first end and a second end, and a second end coupled to the second region of the metal structure,
a second low pass filter at the second slit, the second low pass filter having a third end and a fourth end, the third end coupled to the second region of the metal structure, and the fourth end coupled to the third region of the metal structure, and
a first terminal coupled to the first end of the first low pass filter; and

a cover configured to cover at least one surface of the mobile device, the cover including a second metal material, and the cover and at least a portion of the frame configured to operate as a second antenna for a second wireless communication.

13. The housing of claim 12 , wherein the cover includes,
a metal region,
an insulating region adjacent to an one side of the mobile device and
a second terminal on the metal region, the second terminal being adjacent to the insulating region such that the insulating region is between the first terminal and the second terminal.

14. The housing of claim 13 , wherein the housing is configured to perform the second wireless communication by using a signal path provided along the first terminal, the first low pass filter, the second region of the metal structure, the second low pass filter, the third region of the metal structure, a portion of the metal region and the second terminal.

15. The housing of claim 12 , wherein the first low pass filter includes,
