Abstract

Various embodiments of a multi-mode antenna are described. The antenna is preferably constructed having a first inductor coil and a second inductor coil. A plurality of shielding materials are positioned throughout the antenna to minimize interference of the magnetic fields that emanate from the coils from surrounding materials. The antenna comprises a coil control circuit having at least one of an electric filter and an electrical switch configured to modify the electrical impedance of either or both the first and second coils.
