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

摘要

A method of providing 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 providing an antenna, the method comprising:
a) forming a first coil with a first conductive wire having N1 number of turns with spaced apart first and second first coil ends contactable to a substrate surface, wherein the first coil is capable of generating a first inductance; b) forming a second coil with a second conductive wire having N2 number of turns with spaced apart first and second coil ends, the second coil capable of generating a second inductance positioned within an inner perimeter formed by the first coil; c) 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 first or second coils; and d) selecting a connection between two of the first, second and third terminals to tune an inductance that is generatable by the antenna.
