N2 - This paper presents an investigation of tag antenna<br/>performance in the scenario of a passive RFID tag placed on an<br/>asphalt road and inquired by readers in vehicles. Three types<br/>of antennas were chosen and their properties were studied for<br/>various dielectric properties of the asphalt paving. Water on<br/>the pavement (e.g. due to rainfall) was also taken into account,<br/>with various layer thicknesses. Based on the results of numerical<br/>experiments performed using the finite-difference time-domain<br/>(FDTD) method we demonstrate how the communication range<br/>between the tag and a reader varies depending on the materials<br/>surrounding the tag and wave polarization.
