METHOD OF FABRICATING A SINGLE STRUCTURE MULTI MODE ANTENNA FOR WIRELESS POWER TRANSMISSION USING MAGNETIC FIELD COUPLING

摘要

A method of fabricating a single structure multiple mode antenna is described. The antenna is preferably constructed having a first inductor coil that is electrically connected in series with a second inductor coil. The antenna is constructed having a plurality of electrical connections positioned along the first and second inductor coils. A plurality of terminals is connected to the electrical connections that facilitate numerous electrical connections and enables the antenna to be selectively tuned to various frequencies and frequency bands.

1. A method of fabricating an antenna, the method comprising:
a) providing a substrate having a surface composed of an electrically insulative material; b) forming a first coil of a first conductive wire having N1 number of turns with spaced apart first and second first coil ends that are disposed on the substrate surface, wherein the first coil is capable of generating a first inductance; c) forming a second coil of a second conductive wire having N2 number of turns with spaced apart first and second second coil ends, the second coil capable of generating a second inductance positioned within an inner perimeter formed by the first coil on the substrate surface; d) electrically connecting a first terminal to the first end of the first coil, electrically connecting a second terminal to the second end of the second coil and electrically connecting a third terminal along either of the second or third coils; and e) selecting an electrical connection between two of the first, second, and third terminals to selectively tune an inductance generatable by the antenna.
