1. An antenna structure, comprising:

  • a printed circuit board (PCB);

    at least one planar inverted F antenna (PIFA), configured within a top and bottom layer of the PCB, including a port coupled with the PCB to provide wireless power signals for radiation by the at least one PIFA; and

    at least one artificial magnetic conductor (AMC) cell configured within the PCB, the at least one AMC cell comprising;

    a backing metal layer arranged in a first inner layer of the PCB, andan AMC metal layer formed in a second inner layer of the PCB, the AMC metal layer having a predetermined shape,wherein the AMC metal layer is configured to reflect the wireless power signals radiated by the PIFA.
