Test on 13MHz RFID Tag-RLB Test Method

Radio Frequency Identification (RFID), a wireless RF identification system, utilizes radio frequency (electromagnetic sensing,microware, etc.) to conduct the transmission, identification and swapping of wireless information. A complete RFID includes electronic tag (Tag), reading device (Reader) and main computer (Host). This application uses RLB to test the common 13MHz RFID Tag. This test method can also be applied for production line to rapidly compare the result with Golden Sample.

 

The Basic Understanding of the Test

The test method of RFID Tag utilizes RLB and RFID Tag fixture. After connecting TG, fixture and RF terminal, normalize the signal and place DUT at the center of fixture to obtain Tag's frequency range.

This test method aims at obtaining the Return Loss data of DUT to find out its main operating frequency. The amplitude difference under TG Normalize line is the real test difference.

Required Equipment
