Abstract
Chipped and chipless RFID (Radio frequency identification) sensors for quality monitoring of light weight concrete (LWC) using the radar equation are presented. In this paper, a printed loop tag with a meander-line is employed as a chipped RFID sensor and a dual printed perpendicular square loop tag is employed as a chipless RFID sensor. The optimum parameters of the proposed RFID sensors are obtained using the CST Microwave Studio program. Both RFID sensors with/without IC chip are used to improve the accuracy of dielectric material determination. In addition, the relation between the read range (Rmax) and the real part of dielectric constant (r) is studied. It is found that it can be used to determine the dielectric constant of LWC.
