Abstract :
In this work, we propose a novel design of equivalent antenna to capture the characteristics of the human induced current by 13.56 MHz RFID exposure. The proposed antenna model is loop-type antenna which consists of two perpendicular small circular loops. The proposed structure is a loop-type antenna that can sense the magnetic near fields. The proposed antenna model is verified by the comparison with the induced current in human body. The currents are measured by HI-3702 clamp-type induced current meter.
