Spindle supported near field communication device
First Claim
1. A spindle supported near field communication (NFC) device comprising:
- 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, wherein the core portion and the coil disposed around the core portion are positioned between the first ferromagnetic flange portion and the second ferromagnetic flange portion.
