Dual-Band Channel Measurements for an Advanced Tyre Monitoring System

Abstract—Due to the legal situation in some states and the beneficial effects on vehicular safety, fuel consumption and comfort issues, tyre pressure monitoring systems became very popular in the recent years. Despite this situation, few measurement data about the propagation channel between the sensor units and the vehicle’s reader antenna are available, especially for frequency bands above 433 MHz and for reader antennas mounted on the vehicle’s bottom plate. In this contribution we present static channel measurements for an advanced tyre monitoring system (ATMS) in the 868 MHz and the 2.45 GHz bands, carried out with a vehicle equipped with a single dual-band receive antenna at the vehicle bottom. ATM systems obtain sensor data directly in the tyre, so the sensor unit antennas were placed at the tyre sidewalls.
