Abstract

A structure for wireless communication having a plurality of conductor layers, an insulator layer separating each of the conductor layers, and at least one connector connecting two of the conductor layers wherein an electrical resistance is reduced when an electrical signal is induced in the resonator at a predetermined frequency. The structure is capable of transmitting or receiving electrical energy and/or data at various near and far field magnetic coupling frequencies.

First claim

What is claimed is:

1 . An antenna, comprising:
a) a plurality of conductors, wherein each of the plurality of conductors comprises a skin depth and a conductor thickness; b) an insulator separating each of the conductors forming an antenna structure configured to receive or transmit at least one of an electrical energy and data at least at a first frequency; and c) wherein the antenna is activated to receive or transmit the at least one of the electrical energy and data after an identification code is received.

2 . The antenna of claim 1 , wherein at least two of the plurality of conductors are connected by a connector.

3 . The antenna of claim 1 , wherein at least one of the plurality of conductors comprises at least one of a conductive tape, a conductive ribbon, and a deposited metal.

4 . The antenna of claim 1 , wherein the antenna structure has a cross-section geometry oriented perpendicular to its thickness of a polygon shape.

5 . The antenna of claim 1 , wherein the electrical energy comprises at least one of an electrical voltage, an electrical current, and an electrical power.

6 . The antenna of claim 1 , wherein the data comprises at least one of an electric signal, an electrical current, and an electrical voltage.

7 . The antenna of claim 1 , wherein the antenna is configured to transmit or receive the electrical energy and/or the data at a second frequency that is different than the first frequency.

8 . The antenna of claim 7 , wherein the first or second frequency ranges from about 10 kHz to about 50 MHz.

9 . The antenna of claim 7 , wherein the first or second frequency ranges from about 50 MHz to about 10 GHz.

10 . The antenna of claim 1 , wherein the skin depth of a first or second conductor is dimensioned to be about the same as or less than the thickness of the respective first or second conductor.

11 . The antenna of claim 1 , wherein the skin depth of a first or second conductor ranges from about one-half to about the same as the thickness of the respective first or second conductor.

12 . The antenna of claim 1 , wherein the thickness of a first or second conductor is dimensioned to range from about equal to the skin depth to about twice the skin depth of the respective first or second conductor.

13 . The antenna of claim 1 , wherein the plurality of conductors are composed of an electrically conductive material.

14 . The antenna of claim 1 , wherein the data may be encoded or decoded to represent an alpha numeric string, an ASCII string, a binary code, or combinations thereof.

15 . The antenna of claim 1 , wherein at least one insulator is composed of an electrically insulative material.

16 . The antenna of claim 1 , wherein the data comprises a sequence of electrical voltages, electrical currents or combinations thereof.

17 . The antenna of claim 1 , wherein the antenna is configured to exhibit a quality factor greater than about 50.

18 . The antenna of claim 1 , wherein each of the plurality of conductors and the insulator of the antenna structure have at least one turn.

19 . The antenna of claim 1 , wherein the identification code comprises a digital data signal, an alpha numeric string, a binary code, an electrical power, an electrical voltage, an electrical current, or combinations thereof.

20 . The antenna of claim 1 , wherein a circuit configured to operate the antenna is electrically connected thereto.
