Abstract:
In certain embodiments, a hybrid radio frequency identification (RFID) tag includes circuitry, a battery, and a first antenna. The circuitry includes one or more passive RFID elements and one or more semi-active RFID elements operable to transmit and receive communications to and from one or more RFID tag tracking systems. The battery is coupled to the one or more semi-active elements. The first antenna is coupled to the passive RFID elements and to the semi-active RFID elements, the first antenna comprising a shape that defines a first open area and a second open area. The circuitry is positioned within one of the first and second open areas defined by the shape of the first antenna, and the battery is positioned within the other of the first and second open areas defined by the shape of the first antenna.
