1. An antenna comprising:

  • a reference conductive layer to emit electromagnetic energy in response to an electrical signal received at the reference conductive layer;

    a radiating conductive layer comprising at least one slot opening;

    one or more intermediate conductive layers disposed between the reference conductive layer and the radiating conductive layer; and

    two or more dielectric layers, the two or more dielectric layers comprising at least a first dielectric layer disposed between the reference conductive layer and the one or more intermediate conductive layers and a second dielectric layer disposed between the one or more intermediate conductive layers and the radiating conductive layer;

    wherein each of the one or more intermediate conductive layers comprise at least one opening substantially devoid of conductive material.
