Performance Study of Detectability of RFID System With Varying Atmospheric Conditions

摘要

Now a days Radio Frequency Identification (RFID) system has established itself as reliable solution for number of applications like health monitoring system, toll collection at toll plaza, natural habitat monitoring etc. In RFID system data can be stored in tag, which can be read by the RFID reader. But one major issue with this technology is that its detectability may get affected with varying atmospheric conditions like temperature, humidity, presence of soil (in case defense purpose). So now days the prime focus of researcher is to study the effect of varying atmospheric conditions on propagation of Electromagnetic wave to predict the behavior of RFID system. This paper provides the behavioral pattern of RFID system if it is being used in varying atmospheric conditions. We considered arid atmospheric condition for the study on low frequency RFID system. Effects of two parameters on read range (maximum distance between RFID transmitter and receiver) of RFID system were observed i.e. varying temperature and soil layer thickness between transmitter and receiver.
