Abstract
Various embodiments of inductor coils, antennas, and transmission bases configured for wireless electrical energy transmission are provided. These embodiments are configured to wirelessly transmit or receive electrical energy or data via near field magnetic coupling. The embodiments of inductor coils comprise a figure eight configuration that improve efficiency of wireless transmission efficiency. The embodiments of the transmission base are 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 in contact with or adjacent to the transmission base.
