1. An antenna comprising:

  • an electromagnetic band gap (EBG) ground plane that includes metamaterial; and

    a plurality of slot antennas configured to transmit a wireless power signal having a wavelength to a wireless power receiver, each slot antenna of the plurality of slot antennas coupled with a via that extends from the slot antenna to the EBG ground plane and positioned approximately one-quarter of the wavelength above the EBG ground plane,wherein;

    the metamaterial of the EBG ground plane is configured to increase power output of the plurality of slot antennas and reduce cross-coupling between the plurality of the slot antennas,the vias are configured to conduct the wireless power signal, andthe wireless power receiver is configured to convert the wireless power signal into usable power.
