Flat antennas having two or more resonant frequencies for use in wireless power transmission systems

Abstract:

The various embodiments described herein include methods, devices, and systems for wireless power transmission. In one aspect, a wireless power transmission system includes an antenna component configured to transmit and/or receive electromagnetic waves, such as power waves, the antenna component having at least two conductive plates positioned on a same plane, where: (1) the at least two conductive plates form a monopole antenna configured to transmit and/or receive electromagnetic waves in a first frequency range, (2) the at least two conductive plates are positioned such that a gap exists between the at least two conductive plates, thereby forming a capacitor, and (3) the at least two conductive plates and the gap form a loop antenna configured to transmit and/or receive electromagnetic waves in a second frequency range.
