RFID Copper Etching HF Antenna (HF Antenna), is one of our new products, its working frequency: 13.56±0.2MHz. Currently our min line width and line distance could meet 0.1mm， etching accuracy ±0.03mm. Compare with Aluminum Etching antenna, Copper Antenna get higher accuracy, Anti-high temperature, and much more durable.
