RFID Antennas are used to receive/transmit electromagnetic waves. These antennas are designed to be used at specific radio frequencies by devices that identify and track items using electronic labels (tags). The characteristics are frequency, features, and size/dimensions. The frequency ranges from 125 kHz to 5.85 GHz with the features being bistatic/6 dBi gain max, compact size, LR loop, LR or MR/loop, LR/gate, monostatic/6 dBi gain max, MR/handheld loop or pad, near field communication (NFC), panel with IP50 housing, PR/pad, SMA style, and UHF LR/circular polarized.
