RFID Antennas

As a key component of radio frequency identification systems, RFID antennas perform the dual functions of electromagnetic wave energy conversion and signal transmission. Their performance directly determines the tag’s recognition range, read/write stability, and anti-interference capabilities.

 

1. What are the Technical Features of RFID Antennas?

1) Frequency Adaptability

Low Frequency (LF, 125-134kHz): Short-range, high penetration, suitable for animal identification.

High Frequency (HF, 13.56MHz): A balanced option, commonly used in access control systems.

Ultra-High Frequency (UHF, 860-960MHz): Long-range (10m+) batch reading, mainstream in logistics.

 

2) Polarization

Linear Polarization: Highly directional, suitable for fixed readers.

Circular Polarization: Multi-angle recognition, suitable for mobile applications.

 

3) Material Innovation

Flexible conductive ink-printed antennas enable integration into wearable devices, while ceramic substrate antennas meet the requirements of high-temperature industrial environments.
