Experimental Study on RFID Antenna Reading Areas in a Tunnel System

الملخص EN

We study optimized antenna reading area mappings for a radiofrequency identification- (RFID-) based access monitoring system, used in an underground nuclear waste storage facility.

We shortly introduce the access monitoring system developed for the ONKALO tunnel in Finland and describe the antenna mounting points as well as the research area.

Finally, we study the measurement results of the antenna reading areas and factors that affect the reading area size.

Based on our results, in addition to antenna location and direction, absorption to obstacles, reflections, diffraction, scattering, and refraction affect the antenna reading area.
