Abstract

A portable storage device is provided that includes a first heat sink and a second heat sink, and a printed circuit board disposed between the first heat sink and the second heat sink. The printed circuit board includes a top side, a bottom side, and a peripheral edge disposed between the top side and the bottom side, and a side-plated antenna disposed on the peripheral edge of the printed circuit board. The side-plated antenna is configured to transmit and receive radio frequency signals.

Claims (28)

1. A portable storage device comprising:

a printed circuit board comprising:

a top side, a bottom side, and a peripheral edge disposed between the top side and the bottom side;

a plurality of portions of a conductive material disposed on the peripheral edge; and

a plurality of equally sized traces disposed in pairs, one portion of each pair disposed on the top side and one portion of each pair disposed on the bottom side, wherein the peripheral edge between each pair is non-conductive material, each of the trace pairs electrically connected to a corresponding pair of the portions of the conductive material,

wherein the plurality of portions of a conductive material and the plurality of traces comprise a meander structure radio frequency antenna that is partially on the peripheral edge and partially on the top side and the bottom side for the portable storage device.

2. The portable storage device of claim 1 , wherein the meander structure radio frequency antenna is electroplated on the peripheral edge of the printed circuit board.

3. The portable storage device of claim 1 , wherein the meander structure radio frequency antenna comprises a conductive material.

4. The portable storage device of claim 1 , further comprising a radio frequency feed input terminal on the top side or the bottom side of the printed circuit board, the radio frequency feed input terminal coupled to the plurality of portions of a conductive material.

5. The portable storage device of claim 1 , wherein the meander structure radio frequency antenna comprises an inverted-F antenna.

6. The portable storage device of claim 1 , wherein the meander structure radio frequency antenna comprises a monopole antenna.

7. The portable storage device of claim 1 , wherein the printed circuit board is disposed between a top cover, a bottom cover, and a side portion, wherein the top cover and the bottom cover each comprise a metal and the side portion comprises a non-metallic material.

8. The portable storage device of claim 7 , wherein the side portion comprises a first portion that is substantially parallel to the peripheral edge of the printed circuit board.

9. The portable storage device of claim 7 , wherein the side portion comprises a first portion that is substantially perpendicular to the top cover and the bottom cover.

10. The portable storage device of claim 1 , wherein the meander structure radio frequency antenna comprises one or more of a Bluetooth Low Energy antenna, a WiFi antenna, and a UHF antenna.

11. A portable storage device comprising:

a housing comprising a top cover and a bottom cover, each comprising metal; and

a printed circuit board disposed within the housing, the printed circuit board comprising:

a top side, a bottom side, and a peripheral edge disposed between the top side and the bottom side, the peripheral edge substantially perpendicular to the top cover and the bottom cover;

a plurality of portions of a conductive material disposed on the peripheral edge; and

a plurality of equally sized traces disposed in pairs, one portion of each pair disposed on the top side and one portion of each pair disposed on the bottom side, wherein the peripheral edge between each pair is non-conductive material, each of the trace pairs electrically connected to a corresponding pair of the portions of the conductive material,

wherein the plurality of portions of a conductive material and the plurality of traces comprise a meander structure radio frequency antenna that is partially on the peripheral edge and partially on the top side and the bottom side configured to transmit and receive radio frequency signals.

12. The portable storage device of claim 11 , wherein the meander structure radio frequency antenna is electroplated on the peripheral edge of the printed circuit board.

13. The portable storage device of claim 11 , wherein the meander structure radio frequency antenna comprises a conductive material.

14. The portable storage device of claim 11 , wherein the meander structure radio frequency antenna comprises an inverted-F antenna.

15. The portable storage device of claim 11 , wherein the housing further comprises a side portion that comprises a first portion that is substantially parallel to the peripheral edge of the printed circuit board.

16. The portable storage device of claim 11 , wherein the first portion is substantially perpendicular to the top cover and the bottom cover.

17. The portable storage device of claim 11 , wherein the meander structure radio frequency antenna comprises one or more of a Bluetooth Low Energy antenna, a WiFi antenna, and a UHF antenna.
