Advantenna-p16 is a compact RFID UHF 6 elements patch antenna with circular polarization and a radiation pattern characterized by a 20° beam width in the direction of the antenna long edge and 90o in the direction of the antenna short edge. This radiation pattern makes this antenna ideal for many RFID applications such as time keeping of sport events, marathons, race timing, overhead loss prevention systems, portals, corridors, doors, toll systems and vehicle tracking.
