product description

BRT-38 PCB anti-metal tag/label designed and manufactured by Broadradio is a label specially designed for complex environments such as metal. It has a circular design, long reading distance, high sensitivity, small size and convenient installation. It is especially suitable for various metals. The environment can be conveniently applied to metal asset equipment management, gun management, medical device management and other occasions.

Factors affecting the reading distance of RFID electronic tags

1. It is related to the radio frequency power of the RFID reader. If the radio frequency power is small, the reading distance will be close. On the contrary, if the power is high, the reading distance will be far;

2. It is related to the gain of the RFID reader antenna, the gain of the reader antenna is small, the reading distance is close, anyway, the gain is high and the reading distance is long;

3. It is related to the degree of coordination between the RFID tag and the antenna polarization direction and relative angle. The direction is consistent and the degree of coordination is high, and the reading and writing distance is far. On the contrary, if it does not cooperate, the reading distance is short;

4. It is related to the unit attenuation of the feeder. The larger the attenuation, the closer the reading and writing distance. On the contrary, the smaller the attenuation and the longer the reading distance;

5. It is related to the total length of the feeder connecting the reader and the antenna. The longer the feeder, the shorter the reading and writing distance. On the contrary, the shorter the feeder and the longer the reading distance.
