The radio frequency identification (RFID) is a wireless communications that lets computer reads the identity to tag at 2:45 GHz can be fast identified the high speeds at 3 meters read range guaranteed at speeds of 100 km/hr. This paper used the model for expressway by supposing receiver moves to fixed transmitter, the microstrip antenna was used for both transmitter and receiver, The Friispsilas transmission formula is used for analysis. We considered characteristics of antennas performance at each distance transmission channel, magnitude and phase channel transfer function, bit error rate, path loss and rms delay spread were the results of experimental. This technique is very to useful for analyzed the signal performance and transmission signal in the RFID networks.
