Abstract: Systems, devices, and related methods for shaping near field interrogation signals are discussed herein. An example spindle supported near field communication (NFC) device includes a spindle configured to mount to a mounting surface, the spindle having an axis of rotation; a beam shaping NFC device including: a ferromagnetic core portion coaxial with the spindle; a coil disposed around the core portion, the coil to generate a near field interrogation signal; a first ferromagnetic flange portion to direct the near field interrogation signal in directions extending radially from the axis and to restrict the near field interrogation signal from extending in a first axial direction associated with the axis; and a second ferromagnetic flange portion to direct the near field interrogation signal in the directions extending radially from the axis and to restrict the near field interrogation signal from extending in a second axial direction associated with the axis.

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.
