Abstract:
An antenna array for detecting a wireless article associated with an object comprising:a plurality of flexible substrates each defining peripheral edges; a plurality of antenna loops each disposed on one of the flexible substrates, wherein the flexible substrates are adapted to be hung to define a detection region in which said plurality of antenna loops transmit and receive electromagnetic signals and through which nix the object and associated wireless tag may pass, wherein each antenna loop includes a single turn of a strip conductor disposed on the flexible substrate along the peripheral edges thereof, and wherein each antenna loop transmits and receives electromagnetic signals; a processor for causing electromagnetic signals to be transmitted and for processing at least received signals for detecting the wireless article associated with the object; and means coupling said plurality of antenna loops and said processor for coupling at least the transmitted and received signals therebetween.
