Indoor measurement and modeling of RFID transmission loss at 5.8 GHz with human body

The radio frequency identification technology in frequency band at 5.8 GHz is becoming the important part of a high-speed data rate in the fields of narrow band application radio wave and in short range wireless communication system. According, the best performance of effects with human body in an indoor environment for the wireless body area networks are necessary to study. This paper, an experimental study and analyze of effects in the radio frequency identification performance of transmission signal with human body. Furthermore, we considers the characteristics of human body in each distances by using the vector network analyzer, and the microstrip antenna for both transmitter and receiver antennas. Therefore, this experiment will be benefit for researching and developing communications system of RFID propagation channel with wireless body area networks.
