Abstract

Claims (26)

1. A system for reading electronic animal tags comprising:

a plurality of two or more readers, each reader located at or near a wall of a respective plurality of races;

wherein each reader has at least one antenna;

wherein the antenna in a reader is associated with a single race to produce an electromagnetic field spanning that race;

each reader is impeded from transmitting or receiving information to or from an animal tag not located in that respective race by at least one electromagnetic shield;

each reader being longitudinally offset with respect to at least one other reader in the plurality of readers.

2. The system of claim 1 , wherein for every race in the plurality of races, there are two readers with antenna associated with that race.

3. The system of claim 1 , wherein the two readers associated with a specific race are longitudinally offset from one another.

4. The system of claim 1 , wherein each reader is impeded by at least two magnetics shields.

5. A system according to claim 1 , wherein each reader constitutes a part of a panel, and wherein the respective panels of the two or more readers are identical to one another.

6. The system of claim 5 , wherein the panel is formed at least in part of plastic or fiberglass.

7. The system of claim 1 , wherein each antenna comprises a coil, wherein each coil is substantially circular or pentagonal in shape, and wherein each coil is configured to be used in a Helmholtz configuration.

8. The system of claim 1 , wherein the electromagnetic shield comprises a conducting mesh, wherein the conducting mesh is electrically grounded or electrically floating, and wherein the apertures of the conducting mesh are elliptical or rectangular.

9. The system of claim 8 , wherein the conducting mesh is configured to impede electromagnetic radiation of frequencies falling within a range of at least one of:

918-926 MHz;

13.553-13.567 MHz;

6.765-6.769 MHz; and

125-148.5 KHz.

10. A method of constructing a reader according to claim 1 , comprising:

providing two flat structures;

providing at least one antenna in or on one of the flat structures;

providing an electromagnetic shield in or on one of the flat structures; and

joining the two flat structures together.

11. The method of claim 10 , where providing at least one antenna comprises winding an electrical conductor onto at least one of the flat structures.

12. The method of claim 10 , wherein providing an electromagnetic shield comprises affixing an electromagnetic shield to at least one of the flat structures.

13. The method in claim 10 , wherein the joining comprises laminating the two flat structures together.
