Abstract
Systems, devices, and related methods for shaping near field interrogation signals are discussed herein. Some embodiments may provide for a spindle supported near field communication (NFC) device including a spindle configured to mount to a mounting surface, and a beam shaping NFC device. The beam shaping NFC device may include: a ferromagnetic component including a core portion, wherein the core portion defines a core cavity and the spindle is inserted within the core cavity; and a wire coil disposed around the core portion. The ferromagnetic component may be configured to concentrate near field interrogation signals generated by the wire coil toward a near field interrogation region and away from the mounting surface, or other components capable of causing interference or degradation of the near field interrogation signals.
