Popis:	96 This thesis is devoted to the design, fabrication and testing of tags for passive UHF radio-frequency identification (RFID) system. RI-UHF-STRAP-08 form TI is identified at the chip IC strap for the tag due to its relative low DC power consumption. While the chip impedance of the tag IC was characterized through TRL calibrated measurement system, complex conjugate matching technique at desired frequency was adopted. In order to achieve good power match, across the entire frequency band of operation, quasi log-periodic antenna scheme was implemented. The tested maximum readable was measured to be 4.5m at EIRP=4W output level.
