In this contribution we introduce geometric based modeling of carrier crosstalk between transmitter and receiver of an Ultra High Frequency (UHF) Radio Frequency Identification (RFID)reader. We take two paths into account: a direct static crosstalk path between transmitter and receiver, and a backscatter path between the transmit antenna of the RFID reader, a transponder and the receive antenna of the RFID reader. While the positions of the reader antennas are fixed, the position of the transponder is varied in simulation based on the movement of a transponder on a conveyor belt. Furthermore, also the compensation of this crosstalk is simulated and results are presented. Finally, for dedicated scenarios we compare simulation results with measurements carried out with our multi antenna RFID research environment which incorporates active crosstalk compensation.
