CLAIMS

1. A device, comprising:

a first body and a second body, wherein the bodies are configured to be displaceable when using the device;

wherein the first body comprises:

a first conductive portion of a cover of the device configured as an antenna of the device;

a second conductive portion of the cover configured as a ground of the antenna; and

a dielectric slot in the cover, which is configured between the first and the second portions;

wherein the second body comprises:

a first conductive portion of a second cover of the device;

a second conductive portion of the second cover; and

a dielectric slot in the second cover, which is configured between the first and the second portions;

wherein a shape of the first and the second conductive portion of the first body and the dielectric slot of the first body aligns with a shape of the first and the second conductive portion of the second body and the dielectric slot of the second body, when the bodies are on one another.

2. The device of claim 1, wherein the first conductive portion of the second body is configured for additional antenna diversity for the antenna and the second conductive portion of the second body is configured for the additional antenna diversity as additional ground.

3. The device of claim 1, wherein the shapes are symmetrical; or wherein the shapes are identical.

4. The device of claim 1, wherein the device is foldable so that the first and the second bodies are attached by a hinge.

5. The device of claim 4, wherein the shapes are symmetrical with respect to an axis of rotation of the hinge; or

wherein when the bodies are in a folded position so that the bodies are on one another both bodies are configured as the antenna, and when the bodies are in an unfolded position the first body is configured as the antenna; or

wherein when the bodies are in a folded position so that the bodies are on one another both bodies are configures as the antenna, and when the bodies are in an unfolded position both bodies are configured as the antenna.

6. The device of claim 1, wherein the first and the second bodies are detachable.

7. The device of claim 1, wherein each body further includes a third conductive portion configured as the antenna and a second dielectric slot configured between the third conductive portion and the second conductive portion.

8. The device of claim 1, wherein a width of the dielectric slot is substantially smaller than a width of the first conductive portion.

9. The device of claim 1, wherein the first conductive portion is configured as multiple antennas of the device.

10. The device of claim 1, wherein the dielectric slot is configured as one of the following: horizontal, vertical, a freeform line, an oblique line, branching, and dual slots.

11. The device of claim 1, wherein an edge of the first conductive portion of the first body and an edge of the first conductive portion of the second body are located at a distance from each other.

12. The device of claim 11, wherein the distance is larger when the device is in an unfolded position than when the device is in a folded position.

13. A mobile device, comprising:

a first body and a second body, wherein the bodies are configured to be displaceable with respect to each other when using the mobile device, wherein each body comprises:

a first conductive portion of a cover of the mobile device configured as an antenna of the device;

a second conductive portion of the cover configured as a ground of the antenna; a dielectric slot in the cover, which is configured between the first and the second portions;

wherein a design of the first and the second conductive portion of the first body and the dielectric slot of the first body aligns with a design of the first and the second conductive portion of the second body and the dielectric slot of the second body, when the bodies are on one another.

14. A method comprising:

attaching a first and a second body of a device to each other to a folded position so that a shape of a first and a second conductive portion of the first body and the dielectric slot of the first body aligns with a shape of a first and a second conductive portion of the second body and a dielectric slot of the second body, wherein the first body comprises:

the first conductive portion of a cover of the device configured as an antenna of the device;

the second conductive portion of the cover configured as a ground of the antenna; and

the dielectric slot of the cover, which is configured between the first and the second portions;

wherein the second body comprises:

the first conductive portion of the cover of the device;

the second conductive portion of the cover; and

the dielectric slot of the cover, which is configured between the first and the second portions; and

maintaining the attachment, when the device is unfolded to an unfold position, wherein the device is unfoldable to the unfold position so that the first conductive portion of the first body and the first conductive portion of the second body are at a distance from each other. 15. The method of claim 14, wherein the first conductive portion of the first body and the first conductive portion of the second body are configured for additional antenna diversity of the antenna.
