## Abstract

A device for reflecting radio frequency (RF) radiation away from a user of a mobile phone has a metallic plate configured to be positioned between the mobile phone and a decorative and/or protective cover. The metallic plate is positioned over a rear surface of the mobile phone. The metallic plate is removable and non-permanently attached to the mobile phone and the decorative and/or protective cover.

## Claims

### Claim 1

A device for deflecting radio frequency (RF) radiation away from a user of a mobile phone comprising:
a metallic plate configured to be positioned between the mobile phone and at least one of a decorative or protective cover, the metallic plate positioned over a rear surface of the mobile phone, wherein the metallic plate is removable and non-permanently attached to the mobile phone and the at least one of a decorative or protective cover and wherein the metallic plate includes:
a copper plate; and
a powder coating formed over the copper plate.

### Claim 2 (depends on 1)

The device of claim 1, wherein the copper plate is configured to cover an entire area of the rear surface of the mobile phone.

### Claim 3 (depends on 1)

The device of claim 1, wherein the metallic plate comprises a clear coat formed over the powder coating.

### Claim 4 (depends on 3)

The device of claim 3, wherein the metallic plate comprises a slip resistant material applied to at least one surface of the clear coat.

### Claim 5 (depends on 1)

The device of claim 1, wherein the metallic plate comprises indicia formed on the powder coating.

### Claim 6 (depends on 1)

The device of claim 1, wherein the copper plate has undulating edges.

### Claim 7 (depends on 1)

The device of claim 1, wherein the copper plate has saw-tooth edges.

### Claim 8 (depends on 1)

The device of claim 1, wherein the copper plate has a thickness of 1/32 to ⅛ inches.

### Claim 9

A device for deflecting electromagnetic radio frequency (RF) radiation away from a user of a mobile phone comprising:
a metallic plate configured to be positioned between the mobile phone and a cover portioned over a rear surface of the mobile phone, wherein the metallic plate is removable and non-permanently attached to the mobile phone and the cover, wherein the metallic plate includes:
a copper plate configured to cover the rear surface of the mobile phone where RF signals are radiating from the mobile phone when the mobile phone is receiving/transmitting RF signals; and
a powder coating formed over the copper plate.

### Claim 10 (depends on 9)

The device of claim 9, wherein the metallic plate comprises a clear coat formed over the powder coating.

### Claim 11 (depends on 10)

The device of claim 10, wherein the metallic plate comprises a slip resistant material applied to at least one surface of the clear coat.

### Claim 12 (depends on 9)

The device of claim 9, wherein the metallic plate comprises indicia formed on the powder coating.

### Claim 13 (depends on 9)

The device of claim 9, wherein the copper plate has undulating edges.

### Claim 14 (depends on 9)

The device of claim 9, wherein the copper plate has saw-tooth edges.

### Claim 15 (depends on 9)

The device of claim 9, wherein the copper plate has a thickness of 1/32 to ⅛ inches.

### Claim 16

A device for deflecting radio frequency (RF) radiation away from a user of a mobile phone comprising:
a metallic plate configured to be positioned between the mobile phone and a cover portioned over a rear surface of the mobile phone, wherein the metallic plate is removable and non-permanently attached to the mobile phone and the cover, wherein the metallic plate includes:
a copper plate configured to cover the rear surface of the mobile phone where RF signals are radiating from when the mobile phone is receiving/transmitting RF signals;
a powder coating formed over the copper plate;
a clear coat formed over the powder coating; and
a slip resistant material applied to at least one surface of the clear coat.

### Claim 17 (depends on 16)

The device of claim 16, wherein the metallic plate comprises indicia formed on the powder coating.

### Claim 18 (depends on 16)

The device of claim 16, wherein the copper plate has undulating edges.

### Claim 19 (depends on 16)

The device of claim 16, wherein the copper plate has saw-tooth edges.

### Claim 20 (depends on 16)

The device of claim 16, wherein the copper plate is rectangular in shape.
