CLAIMS
1. A device comprising:
a first antenna layer coupled to a first side of a base; and
a second antenna layer coupled to a second side of the base and the first antenna layer, the first and second antenna layers configured to at least transmit or receive wireless signals.

2. The device of claim 1 including an inter-connecter to electrically couple first and second antenna layers through the base and a ground connection to electrically couple first antenna layer through the base to a grounding plate.

3. The device of claim 1 including electrical circuitry coupled to the first antenna layer, the electrical circuitry to provide a transmission current to the first antenna layer, where the first antenna layer is configured to propagate the transmission current to generate the wireless signals.

4. The device of claim 3 where the first antenna layer is configured to propagate the transmission current to the second antenna layer, where the second antenna layer is configured to propagate the transmission current to generate the wireless si 'togn* als.

5. The device of claim 4
where the first antenna layer includes multiple vertical members, and the second antenna layer includes multiple vertical members which are in substantial alignment with the vertical members associated with the first antenna layer; and where the transmission current propagates in substantially the same direction in vertical members of the first and second antenna layers.

6. The device of claim 1 including electrical circuitry coupled to the first antenna layer, where the first and second antenna layers generate a reception current responsive to wireless signals and propagate the reception current to the electrical circuitry.

7. The device of claim 2

Docket No. 5087-251 6 CD06012 where the first antenna layer includes multiple vertical members, and the second antenna layer includes multiple vertical members which are in substantial alignment with the vertical members associated with the first antenna layer; and
where the reception current propagates in substantially the same direction in vertical members of the first and second antenna layers.

8. A device comprising:
a multi-layer antenna configured to at least transmit or receive wireless signals, the multi-layer antenna including a plurality of antenna layers each to propagate electrical signals in substantially the same direction when transmitting or receiving the wireless signals.

9. The de\ice of claim 8 including an antenna inter-connector to couple two or more antenna layers.

10. The device of claim 8 where each antenna layer includes one or more vertical members, where the vertical members of one antenna layer are aligned with corresponding vertical members from at least another antenna layer.

1 1. The device of claim 10 where the antenna layers are configured to propagate the electrical signals through the aligned vertical members in substantially the same direction when transmitting or receiving the wireless signals.

12. The device of claim 8 including a ground connection to electrically couple at least one antenna layer to a grounding plate.

13. The device of claim 8 including electrical circuitry coupled to at least one of the antenna layers, where the antenna layers generate wireless signals by propagating a transmission current received from the electrical circuitry.

14. The device of claim 13 where the antenna layers generate a reception current responsive to wireless signals and propagate the reception current to the electrical circuitry.
