Tyre Pressure Monitoring System [TPMS] and appropriate sensor concepts operating in the ISM-band at frequencies of 315 MHz and 434 MHz are discussed moderately in the literature. In contrast, the RF-modelling of the whole tyre guard system consisting of the sensor, rim and tyre has not been discussed yet. The measurement results as well as the modelling procedure for a tyre guard sensor on its own, sensor on the rim and with the tyre will be presented. The simulations have been made with the software package FEKO based on the method of moments (MOM). Thus, the TPMS will belong in the future to the standard equipment of a vehicle. For such a system, an increased confidence of operation is necessary. Beside the safety aspects and the accidence avoidance potential of TPMS, the control of the tyre pressure and temperature has a particularly high importance for the reduction of fuel consumption. In order to fulfil the requirements, the RF-design, characterization and modelling of the tyre pressure sensor gains even more on importance not only as a solitary part but more as an integral part of the whole system including the rim, tyre and entire car body.
