High-frequency RFID tag antenna specification and packaging process

- Apr 14, 2018-

High-frequency electronic tags, namely 13.56MHZ RFID electronic tags, can package S50, FM1108, ult series, I-code series, Ntag series, TI series and other chips, can be four-color printing, can be fragile anti-tearing, anti-metal and other processes.

    The inductor of the high-frequency electronic tag at this frequency no longer needs a coil to be wound, and the antenna can be manufactured by etching and printing alive. Sensors generally work by means of load modulation. That is, the voltage across the antenna of the reader/writer changes due to the turning on and off of the load resistor on the inductor, so that the amplitude of the antenna voltage is modulated by the remote sensor. If people control the load voltage on and off through data, then these data can be transmitted from the sensor to the reader. The


High frequency electronic tag features:


1. The operating frequency is 13.56MHz, and the wavelength of this frequency is approximately 22m. The

2. In addition to metallic materials, the wavelength of this frequency can pass through most materials, but it tends to reduce the reading distance. The sensor needs to leave the metal a distance. The

3. The frequency band is recognized worldwide and there are no special restrictions. The

4. The sensor is generally in the form of an electronic tag. The

5. Although the magnetic field at this frequency drops rapidly, it can produce a relatively uniform reading and writing area. The

6. The system has anti-collision characteristics and can read multiple electronic tags at the same time. The

7. Some data information can be written into the tag. The

8. The data transfer rate is faster than the low frequencies and the price is not very expensive. The


The main application of high-frequency electronic tags:

1. Application of library management system

2. Gas cylinder management application

3. Apparel production line and logistics system management and application

4. Three-meter pre-charging system

5. Hotel door lock management and application

6. Large Conference Personnel Channel System

7. Fixed assets management system

8. Management and Application of Pharmaceutical Logistics System

9. Smart shelf management


High-frequency electronic labels comply with international standards:


a) ISO/IEC 14443 Near-Coupled IC Cards with a maximum reading distance of 10 cm.

b) ISO/IEC 15693 decoupled IC card, the maximum reading distance is 1m.

c) ISO/IEC 18000-3 This standard defines the physical layer, anti-collision algorithm and communication protocol for a 13.56 MHz system. The

d) 13.56MHz ISM Band Class 1 defines the 13.56MHz EPC-compliant interface definition
