RFID Antenna SHF 2.40 GHz ~ 2.5 GHz.
Antenna selection is critical to the read rate success. You need to match the antenna(s) to the specific application requirements and to the actual physical environment to obtain the highest read rate.

Most active RFID system are used for locating assets, object and people. As such the Beam coverage needs to be circular rather than linear in order to maximize the read distance.
