In one embodiment, a multi-band near-field antenna for an RFID encoder includes a substrate; an internal coil antenna defined within the substrate; an annular ground plane defined on a first surface of the substrate; a second ground plane defined on an opposing second surface of the substrate, wherein the annular ground plane and the second ground plane form a Faraday cage for the internal coil antenna; and a second antenna disposed on the opposing second surface within the annulus defined by the annular ground plane.
