The technology in the market of IoT (Internet of Things) and T&M (Transportation and Mobility) is growing very fast. In the context of autonomous driving having a network of sensors plays a very important role. A car moving without the human control requires automatic driving manoeuvre systems and this implies demanding requirements on the communication with the sensors installed on the car tires. Currently car tires are already equipped with sensors such as the well-known TPMS (Tire-Pressure Monitoring System). However, different types of additional tire sensors have been identified for improving safety, performance, and environmental impact. SIMULIA CST Studio Suite® has been used for designing an RFID (Radio Frequency IDentification) tag and verifying the performance once it was installed on a car tire. A virtual twin of sensor and tire including a realistic working scenario has been considered in order to have results to be compared to physical testing. This paper shows the analysis results of the RFID tag installed on a car tire in terms of matching and field radiation when interrogated by an RFID reader. Finally, an operative parameter such as the reading distance has been calculated to be compared with real data.
