Abstract: The present platform allows for real-time, accurate situational awareness to an augmented reality (AR) system while using low power, low-maintenance wireless tags. In one aspect, the platform may comprise devices, methods, and systems for providing a visual indication associated with an electromagnetic tag associated with a target object in a physical environment, such as inventory in a warehouse or retail environment. The platform may include a portable electronic device comprising a display, a processing unit, and a radar unit; and at least one wireless tag. The platform may be configured to receive information signals from at least one wireless tag attached to at least one target object in a physical environment of a user, and generate a visual indication associated with the tagged target object based at least on the received information signals, said visual indication at least having information corresponding to the object’s location or position.

Abstract: A radio-frequency responsive device includes a dielectric substrate having a first side and an opposite second side. A Van Atta array reflector is printed on the first side of the dielectric substrate. The Van Atta array reflector reflects an incident signal at a predetermined radio frequency at an incident angle. A conductive ground layer is disposed adjacent the second side of the dielectric substrate. In a method of making a radio-frequency responsive device, a Van Atta array reflector is printed on a first side of a dielectric substrate. A conductive ground layer is applied to a second side of the dielectric substrate, in which the second side is opposite the first side.
