Abstract

The radio frequency identification (RFID) sensor technique applied to detect a different number of reinforced metal bars in a lossy light weight concrete (LWC) is presented. The proposed dipole antenna with inductive loop is employed as an RFID sensor. A different number of reinforced metal bars are studied through the characteristics of the RFID sensor placed on LWC. Simulations are performed using the CST Microwave Studio simulation program. It is found that the reinforced metal bars in LWC have important effects to the antenna gain of the RFID sensor.
