Detection of reinforced metal in light weight concrete structures using an RFID sensor system

Abstract

This paper presents the characteristics of specifically designed tag (SDT) placed on an autoclaved aerated reinforced lightweight concrete to detect and inspect qualities of material products. The proposed SDT is a folded dipole antenna designed using the CST Microwave Studio simulation program. In this system, the SDT acts as a radio frequency identification (RFID) sensor. Simulated results show that the radius of the reinforced metal has important effects to SDT characteristics placed on material under tests.
