Abstract

A storage container assembly includes a container having a metal side wall, and a passive wireless repeater mounted on the side wall. The repeater includes a first antenna on one side of the side wall, a second antenna on an opposite side of the side wall, and an electrical connection between the first antenna and the second antenna. The electrical connection may be in the form of a first connector mounted to the first antenna and a second connector mounted to the second antenna.

Claims

1. A storage container assembly, comprising:

a container including an exterior metal side wall defining an inside of the container; and

a passive wireless repeater mounted on said side wall, said repeater including a first antenna on one side of said side wall, a substantially identically configured second antenna on an opposite side of said side wall, a passive electrical connection extending through said wall and directly interconnected between said first antenna and said second antenna, and a dielectric plastic material which hermetically encapsulates said first antenna, said second antenna, and said passive electrical connection, said passive electrical connection being located within said side wall and coupling said first antenna and said second antenna together within said side wall, said passive electrical connection having a length slightly greater than a thickness of said side wall such that said first antenna lies immediately adjacent to an outside of the container and said second antenna lies immediately adjacent to the inside of the container in a sandwiched arrangement, said first antenna and said second antenna facing approximately 180 degrees away from each other, said passive electrical connection, said first antenna and said second antenna coacting together to passively retransmit a signal from an outside of said container to the inside of the container, or vice versa.

2. The storage container assembly of claim 1, wherein said electrical connection includes a first connector mounted to said first antenna and a second connector mounted to said second antenna.

3. The storage container assembly of claim 2, wherein said first connector includes one of a pin and a socket, and said second connector includes one of a mating pin and socket.

4. The storage container assembly of claim 2, wherein said first connector includes a plurality of pins, and said second connector includes a plurality of mating sockets.

5. The storage container assembly of claim 1, wherein said first antenna and said second antenna are substantially impedance matched.

6. The storage container assembly of claim 1, wherein said dielectric plastic material includes a first dielectric substrate and a second dielectric substrate, said first antenna being mounted on said first dielectric substrate, and said second antenna being mounted on said second dielectric substrate.

7. The storage container assembly of claim 6, wherein said first dielectric substrate and said second dielectric substrate are mounted in a sandwiched arrangement on opposite sides of said side wall using a plurality of fasteners passing through said each of said first dielectric substrate, said side wall and said second dielectric substrate.

8. The storage container assembly of claim 6, wherein said first antenna and said second antenna are each RFID antennas.

16. The antenna assembly of claim 1, wherein said passive electrical connection is a passive plug-in type electrical connection.

18. The antenna assembly of claim 1, wherein said container is a medical device container.

20. The storage container assembly of claim 1, wherein said side wall includes an opening through which said passive electrical connection extends, said first antenna being a single antenna, said second antenna being a single antenna, said first and second antennas being spaced apart and parallel to one another, each of said first and second antennas respectively being centered on said hole such that each of said first and second antennas respectively extends a similar distance away from said hole and thereby said first and second antennas forming an H-configuration together with said passive electrical connection about said hole.

9. An antenna assembly for use with a storage container including an exterior metal side wall defining an inside of the container, said antenna assembly comprising:

a first antenna on one side of said side wall of the storage;

a substantially identically configured second antenna on an opposite side of said side wall;

a passive electrical connection configured to extend through the wall and directly interconnect between said first antenna and said second antenna, said passive electrical connection being located within said side wall and coupling said first antenna and said second antenna together within said side wall, said passive electrical connection having a length slightly greater than a thickness of the side wall such that said first antenna is positionable immediately adjacent to an outside of the container and said second antenna is positionable immediately adjacent to the inside of the container in a sandwiched arrangement, said first antenna and said second antenna facing approximately 180 degrees away from each other, said passive electrical connection, said first antenna and said second antenna coacting together to passively retransmit a signal from an outside of said container to the inside of the container, or vice versa; and

a dielectric plastic material which hermetically encapsulates said first antenna, said second antenna, and said passive electrical connection.

10. The antenna assembly of claim 9, wherein said electrical connection includes a first connector mounted to said first antenna and a second connector mounted to said second antenna.

11. The antenna assembly of claim 10, wherein said first connector includes one of a pin and a socket, and said second connector includes one of a mating pin and socket.

12. The antenna assembly of claim 10, wherein said first connector includes a plurality of pins, and said second connector includes a plurality of mating sockets.

13. The antenna assembly of claim 9, wherein said electrical connection is configured to impedance match between said first antenna and said second antenna.

14. The antenna assembly of claim 9, wherein said dielectric plastic material includes a first dielectric substrate and a second dielectric substrate, said first antenna being mounted on said first dielectric substrate, and said second antenna being mounted on said second dielectric substrate.

15. The antenna assembly of claim 14, wherein said first antenna and said second antenna are each RFID antennas.

17. The antenna assembly of claim 9, wherein said passive electrical connection is a passive plug-in type electrical connection.

19. The antenna assembly of claim 9, wherein the container is a medical device container.
