摘要： An object location system and method is provided for locating objects. The system includes an RFID reader, an angle calculator, and a distance calculator to determine which of a plurality of zones an object is located in or passing through. An RFID tag is affixed with the object that is to be located. The RFID reader transmits signals to the RFID tag and receives backscatter-modulated signals from the RFID tag at one or more RFID antennas. From those received signals, the angle calculator determines an angle of position of the RFID tag relative to the RFID antenna. From the angle of position the zone in which the object is located is determined.

摘要： Methods, systems, and apparatuses for RFID devices, such as reader antennas, are described. A reader antenna includes a quadrature hybrid coupler, a termination element, and an antenna, such as a patch antenna. The quadrature hybrid coupler has first, second, third, and fourth ports. The first port receives an input radio frequency RF signal. The second port outputs a first RF output signal. The third port outputs a second RF output signal. The second RF output signal is shifted in phase by 90 degrees relative to the first RF output signal. The fourth port is coupled to the termination element. The patch antenna has a first point coupled to the first RF output signal and a second point coupled to the second RF output signal. The patch antenna radiates a circularly polarized RF signal due to the received first and second RF output signals. The circularly polarized RF signal may be used to interrogate tags. Furthermore, the reader antenna is integrated into a ruggedized structure that provides environmental protection for the antenna, including providing shock absorption for impacts to the antenna.
