The working frequency of RFID tags is one of its most important features, and tags operating in different frequency bands or frequency points have different characteristics. The frequency bands or frequencies occupied by RFID applications are internationally recognized as being located in the ISM band. Typical operating frequencies are: 125 kHz, 134.2 kHz, 13.56 MHz, 433 MHz, 860-960 MHz, 2.45 GHz, 5.8 GHz, and the like.

So, do you know the characteristics of UHF RFID tags? The following small series will give you an analysis:

1. UHF RFID tags have a high transfer rate and can be read in a large amount in a short period of time.

2. The ultra-high frequency band cannot penetrate many materials, especially water, dust, fog, metal and other materials.

3. The antenna of the RFID tag is generally long and label-shaped. The antenna has two linear and circular polarizations to meet the corresponding application requirements.

4, UHF RFID electronic tags transmit energy through the electric field, the energy of the electric field drops not very fast, but the reading area is not well defined, the reading distance of a certain frequency band is relatively long, the passive can reach about ten meters, mainly through the capacitor Coupling for energy exchange and data transmission.
