Datasheet

Description

This flexible, low-profile NFC antenna is designed for integration into compact devices where reliable 13.56 MHz near-field communication is required. The reverse ferrite layer helps isolate the antenna from nearby conductive components (such as batteries), supporting more consistent communication performance in challenging internal installations.

  • Flexible embedded form factor: ideal for tight mechanical spaces inside product housings
  • Reverse ferrite layer: helps reduce detuning and performance loss near batteries or electronics
  • Adhesive backing: enables quick peel-and-stick integration during assembly
  • Optimized for NFC/RFID use: suited for short-range interaction at 13.56 MHz

Typical applications include:

  • Mobile devices
  • Wearable smart devices
  • Payment terminals
  • Device tracking and ID systems
  • Access control
