Abstract
The present invention relates to a magnetic transmit antenna apparatus comprising: a toroidal core transformer having a primary winding inductively coupled to a secondary winding supplying a low voltage and high current to a magnetic transmit antenna wherein the magnetic transmit antenna includes a wire loop having multiple turns for generating a magnetic field. The toroidal core transformer includes a primary winding that operates in association with the secondary winding to match the impedance of a signal source to the magnetic transmit antenna.
