Abstract
Integrated antenna structures described herein include, as one example, a multi-layered printed circuit board (PCB), including an artificial magnetic conductor (AMC) cell that includes a backing metal layer defining a first inner layer of the multi-layered PCB and an AMC metal layer defining a second inner layer of the multi-layered PCB. The metal layer defining the second inner layer is separated from at least one edge of the multi-layered PCB, and a planar inverted F antenna (PIFA) surrounds the AMC cell. The AMC metal layer is configured to reflect energy radiated by the PIFA. In some embodiments, the energy radiated by the PIFA includes radio frequency waves that can be used by a receiver to power or charge an electronic device.

An antenna structure comprising:
- a multi-layered printed circuit board (PCB), comprising an artificial magnetic conductor (AMC) cell that includes (i) a backing metal layer defining a first inner layer of the multi-layered PCB and (ii) an AMC metal layer defining a second inner layer of the multi-layered PCB, wherein the metal layer defining the second inner layer is separated from at least one edge of the multi-layered PCB;
- and
- a planar inverted F antenna (PIFA) surrounding the AMC cell, wherein the AMC metal layer is configured to reflect energy radiated by the PIFA.
An apparatus for providing 3-dimensional pockets of energy through pocket-forming, the apparatus comprising:
- a multi-layered printed circuit board (PCB), comprising a plurality of artificial magnetic conductor (AMC) cells, wherein each of the AMC cells comprises a backing metal layer and an AMC metal layer defining inner layers of the multi-layered PCB and is separated from at least one edge of the multi-layered PCB, wherein each of the AMC layers is configured to reflect energy independently as radiated by each of a plurality of planar inverted F antennas (PIFAs) to enable pocket-forming of energy,
- wherein each of the PIFAs surrounds at least one AMC cell of the plurality of the AMC cells.
