SINGLE STRUCTURE MULTI MODE ANTENNA HAVING A UNITARY BODY CONSTRUCTION FOR WIRELESS POWER TRANSMISSION USING MAGNETIC FIELD COUPLING

摘要

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

主权项

1. An antenna, comprising:
a) a first coil portion having N1 number of turns with spaced apart first and second first coil portion ends, wherein the first coil portion is capable of generating a first inductance; b) a second coil portion having N2 number of turns with spaced apart first and second second coil portion ends, the second coil portion capable of generating a second inductance positioned within an inner perimeter formed by the first coil portion, wherein the first end of the second coil portion is electrically connected to the second end of the first coil portion, thereby forming a unitary antenna body; c) a first terminal electrically connected to the first end of the first coil portion, a second terminal electrically connected to the second end of the second coil portion and a third terminal electrically connected along either of the first or second coil portions; and d) wherein a tunable inductance is generatable by selecting a connection between two of the first, second and third terminals.
