Abstract

A user equipment (UE) and a method of operating the UE. The UE a display, a cover, a transceiver, and an antenna array. The display partially forms a front surface of the UE. The cover partially forms a side surface of the UE and includes a plurality of electromagnetic strips . The transceiver transmits a signal including a vertical polarization element and a horizontal polarization element. The antenna array is electrically connected with the transceiver and disposed in the space such that, the antenna array is substantially non-overlapped with the cover. The vertical polarization element or the horizontal polarization element is substantially perpendicular to at least one of the plurality of electromagnetic strips.

First claim

What is claimed is:

1. A user equipment (UE) comprising:
a display at least partially forming a front surface of the UE;
a cover at least partially forming a side surface of the UE and including a plurality of electromagnetic strips;
a transceiver disposed in a space surrounded by the cover and configured to transmit a signal including a vertical polarization element and a horizontal polarization element; and
an antenna array electrically connected with the transceiver and disposed in the space such that, when viewed in a direction substantially perpendicular to the side surface, the antenna array is substantially non-overlapped with the cover,
wherein the vertical polarization element or the horizontal polarization element of the signal transmitted from the transceiver to an outside of the UE through the antenna array is substantially perpendicular to at least one of the plurality of electromagnetic strips.

2. The UE of claim 1 , wherein the antenna array includes a dipole antenna array configured to radiate the horizontal polarization element.

3. The UE of claim 2 , wherein the dipole antenna array is substantially perpendicularly disposed to the plurality of electromagnetic strips.

4. The UE of claim 1 , wherein the antenna array includes:
a dipole antenna array configured to form a first beam in a first direction, and
a patch antenna array configured to form a second beam in a second direction.

5. The UE of claim 4 , wherein the first direction is substantially perpendicular to the second direction.

6. The UE of claim 1 , wherein the antenna array includes a patch antenna array configured to radiate the vertical polarization element and the horizontal polarization element.

7. The UE of claim 1 , wherein each of the plurality of electromagnetic strips includes a curved portion corresponding to a curvature of the cover.

8. The UE of claim 1 , wherein at least one of the plurality of electromagnetic strips is connected to another one of the plurality of electromagnetic strips.

9. The UE of claim 1 , wherein the electromagnetic strips are formed therein such that a first end of a gap between two of the plurality of electromagnetic strips is open toward an outside of the cover and a second end of the gap is closed by the cover.

10. The UE of claim 1 , wherein at least two of the plurality of electromagnetic strips are separated from each other by a space having a width of at least one of the plurality of electromagnetic strips.

11. A method of operating a user equipment (UE), the method comprising:
transmitting, by a transceiver disposed in a space surrounded by a cover of the UE, a signal including a vertical polarization element and horizontal polarization element, the cover at least partially forming a side surface of the UE and including a plurality of electromagnetic strips,
wherein an antenna array is electrically connected with the transceiver and disposed in the space such that, when viewed in a direction substantially perpendicular to the side surface, the antenna array is substantially non-overlapped with the cover, and
wherein the vertical polarization element or the horizontal polarization element of the signal transmitted from the transceiver to an outside of the UE through the antenna array is substantially perpendicular to at least one of the plurality of electromagnetic strips.

12. The method of claim 11 , wherein the antenna array includes a dipole antenna array configured to radiate the horizontal polarization element.

13. The method of claim 12 , wherein the dipole antenna array is substantially perpendicularly disposed to the plurality of electromagnetic strips.

14. The method of claim 11 , wherein the antenna array includes:
a dipole antenna array configured to form a first beam in a first direction, and
a patch antenna array configured to form a second beam in a second direction.

15. The method of claim 14 , wherein the first direction is substantially perpendicular to the second direction.

16. The method of claim 11 , wherein the antenna array includes a patch antenna array configured to radiate the vertical polarization element and the horizontal polarization element.

17. The method of claim 11 , wherein each of the plurality of electromagnetic strips includes a curved portion corresponding to a curvature of the cover.

18. The method of claim 11 , wherein at least one of the plurality of electromagnetic strips is connected to another one of the plurality of electromagnetic strips.

19. The method of claim 11 , wherein the electromagnetic strips are formed therein such that a first end of a gap between two of the plurality of electromagnetic strips is open toward an outside of the cover and a second end of the gap is closed by the cover.

20. The method of claim 11 , wherein at least two of the plurality of electromagnetic strips are separated from each other by a space having a width of at least one of the plurality of electromagnetic strips.
