Abstract

A wireless electrical energy transmission system is provided. The system comprises a wireless transmission base configured to wirelessly transmit electrical energy or data via near field magnetic coupling to a receiving antenna configured within an electronic device. The wireless electrical energy transmission system is configured with at least one transmitting antenna and a transmitting electrical circuit positioned within the transmission base. The transmission base is configured so that at least one electronic device can be wirelessly electrically charged or powered by positioning the at least one device external and adjacent to the transmission base.
