This work presents a radio frequency identification (RFID) technology with a carrier inband backscatter modulation scheme. Due to this carrier inband backscatter characteristic, the response signal from the transponder is completely covered by the carrier signal. Up to now, this method is not used for RFID systems. The novel Inband-RFID technology was developed and realized by using a software defined radio (SDR), in particular a GNURadio combined with an Ettus Research universal software radio peripheral (USRP). Considering current RFID research, the super high frequency (SHF) area is employed as frequency domain. In chapter IV it will be shown that the novel RFID technology entails several benefits compared to state-of-the-art RFID technologies.
