A locating and tracking system is provided in which the assets are desired to be located and tracked are associated with either radio frequency (RF) tags or radio frequency identification and radio frequency data communication (RFID/RFDC) devices. Depending on which device is attached to the asset, the other device is located at known locations. The RFID/RFDC devices interrogate and receive signals from the RF tags. The received information is sent to the host computer. With the location of either the RF tags or the RFID/RFDC devices known, the assets may be located and tracked. An improved RF tag antenna design is also provided by using a switching mechanism connected to at least two antennas.
