Antenna with electromagnetic band gap ground plane and dipole antennas for wireless power transfer

Abstract:

An example antenna may include: (i) an electromagnetic band gap (EBG) ground plane, and (ii) a dipole antenna, coupled with a via that extends to the EBG ground plane, configured to transmit a wireless power signal having a wavelength to a wireless power receiver, the dipole antenna being positioned approximately one-quarter of the wavelength above the EBG ground plane. Furthermore, the via is configured to conduct the wireless power signal, and the wireless power receiver is configured to convert the wireless power signal into usable power.
