Abstract

An apparatus and associated method are provided involving a housing having a periphery configured to operate as a second antenna, a third antenna, and a fourth antenna. The periphery includes a top wall having a first slot formed therein, a first side wall having a second slot formed therein, and a second side wall having a third slot formed therein. The top wall is arranged between the first side wall and the second side wall, and a top portion of the periphery is defined between the second slot and the third slot. The top portion is divided into a first top side portion and a second top side portion via the first slot. Further, the first top side portion operates as the second antenna, and the second top side portion operates as both the third antenna and the fourth antenna.

First claim

What is claimed is:

1. A mobile phone, comprising:
a housing having a periphery and a back face, the back face walled around by the periphery along edges of the back face, wherein at least a portion of the housing is conductive and is configured to operate as a first antenna, a second antenna, and a third antenna, the periphery including:
a top wall having a first slot formed therein, wherein the top wall has only one slot formed therein;
a first side wall having a second slot formed therein; and
a second side wall having a third slot formed therein, a width of the first slot, the second slot and the third slot being in a range of 0.5-5 mm, and the top wall arranged between the first side wall and the second side wall, wherein a top portion of the periphery is defined between the second slot and the third slot, wherein the top portion is divided into a first top side portion and a second top side portion via the first slot, wherein the first top side portion operates as the first antenna, wherein the second top side portion operates as both the second antenna and the third antenna, and wherein the first antenna includes a first antenna feed and a first antenna ground, the second antenna includes a second antenna feed and a second antenna ground, and the third antenna includes a third antenna feed and a third antenna ground.

2. The mobile phone of claim 1 , and further comprising:
a configurable element in electrical communication with the first antenna feed.

3. The mobile phone of claim 2 , wherein the configurable element comprises a switch and at least one of a resistive element, a capacitive element, or an inductive element.

4. The mobile phone of claim 1 , wherein the first antenna is configured to be switched between a first mode of operation for operating at a first frequency range and a second mode of operation for operating at a second frequency range.

5. The mobile phone of claim 1 , further comprising:
an insulative material positioned in each of the first slot, the second slot and the third slot.

6. The mobile phone of claim 1 , wherein top edges of the second slot and the third slot are aligned and positioned anywhere within a range of 8-15 mm from the top wall.

7. The mobile phone of claim 1 , wherein at least one of the first antenna, the second antenna or the third antenna is configured to operate as a 4×4 multiple-input-multiple output (MIMO) antenna.

8. The mobile phone of claim 1 , wherein the back face is manufactured from an insulative material.

9. The mobile phone of claim 1 , wherein the first antenna feed, the second antenna feed and the third antenna feed are in electrical communication with a transceiver via a conductive material.

10. The mobile phone of claim 1 , wherein one or more isolations between the first antenna, the second antenna and the third antenna are greater than to 10 dB.

11. A mobile phone, comprising:
a housing having a periphery and a back face, the back face walled around by the periphery along edges of the back face, wherein at least a portion of the housing is conductive and is configured to operate as a first antenna, a second antenna, and a third antenna, the periphery including:
a top wall having a first slot formed therein, with the top wall being divided into only two portions by the first slot;
a first side wall having a second slot formed therein; and
a second side wall having a third slot formed therein, a width of the first slot, the second slot and the third slot being in a range of 0.5-5 mm, and the top wall arranged between the first side wall and the second side wall, wherein a top portion of the periphery is defined between the second slot and the third slot, wherein the top portion is divided into a first top side portion and a second top side portion via the first slot, wherein the first top side portion operates as the first antenna, wherein the second top side portion operates as both the second antenna and the third antenna, and wherein the first antenna includes a first antenna feed and a first antenna ground, the second antenna includes a second antenna feed and a second antenna ground, and the third antenna includes a third antenna feed and a third antenna ground.

12. The mobile phone of claim 11 , and further comprising:
a configurable element in electrical communication with the first antenna feed.

13. The mobile phone of claim 12 , wherein the configurable element includes a switch and at least one of a resistive element, a capacitive element, or an inductive element.

14. The mobile phone of claim 11 , wherein the first antenna is configured to be switched between a first mode of operation for operating at a first frequency range and a second mode of operation for operating at a second frequency range.

15. The mobile phone of claim 11 , further comprising:
an insulative material positioned in each of the first slot, the second slot and the third slot.

16. The mobile phone of claim 11 , wherein top edges of the second slot and the third slot are aligned and positioned anywhere within a range of 8-15 mm from the top wall.

17. The mobile phone of claim 11 , wherein at least one of the first antenna, the second antenna or the third antenna is configured to operate as a 4×4 multiple-input-multiple output (MIMO) antenna.

18. The mobile phone of claim 11 , wherein the back face is manufactured from an insulative material.

19. The mobile phone of claim 11 , wherein the first antenna feed, the second antenna feed and the third antenna feed are in electrical communication with a transceiver via a conductive material.

20. The mobile phone of claim 11 , wherein one or more isolations between the first antenna, the second antenna and the third antenna are greater than to 10 dB.

21. A method, comprising:
creating a housing having a periphery and a back face, the back face walled around by the periphery along edges of the back face, wherein the periphery includes a top wall, a first side wall, and a second side wall, and at least a portion of the housing is conductive and is configured to operate as a first antenna, a second antenna, and a third antenna; and
etching at least three slots in a top portion of the periphery including a first slot formed in the top wall, a second slot formed in the first side wall, and a third slot formed in the second side wall, for dividing the top portion into a first top side portion operating as the first antenna and a second top side portion operating as both the second antenna and the third antenna, wherein the top wall has only one slot formed therein, a width of the first slot, the second slot and the third slot being in a range of 0.5-5 mm, and the first antenna including a first antenna feed and a first antenna ground, the second antenna including a second antenna feed and a second antenna ground, and the third antenna including a third antenna feed and a third antenna ground.
