Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A system comprising:
an antenna system including:
a first elongated ferrite element;
a second elongated ferrite element aligned end-to-end in a same axis with the first elongated ferrite element;
a first coil wrapped around the first elongated ferrite element;
a second coil wrapped around the second elongated ferrite element;
a conductor network connected between the first coil and the second coil; and

a transmit circuit connected to the conductor network, wherein the transmit circuit is configured to provide a first current to the first coil and a second current to the second coil, wherein a first radio frequency (RF) field is generated in the first coil by the transmit circuit and a second RF field is generated in the second coil by the transmitter, the first and second RF fields being emitted in opposition to each other creating an increased field strength perpendicular to the axis between the first and second coils.
