description The radio frequency identification (RFID) technology utilizes the radio frequency (RF) wave for identification of a tagged object. The chipless RFID system operates in the microwave band and exploits the ultra-wideband (UWB) technology. Though the reader of this type RFID system comprises a sophisticated electronic circuitry, the tag does not contain any electronic circuits or silicon chip. The chipless tag is a special arrangement of numbers of microstrip resonators together with antennas, and each resonator represents a logical bit 1 or 0. The detection methodology for microstrip resonator type tag relies on a constant and continuous linear chirp from the UWB RFID reader. The entire UWB (7.5 GHz) needs to be continuous frequency sweep or chirp to detect all the bits from the tag.
