Abstract :
The dead zone of RFID system has been numerically and experimentally investigated. The electric field distribution near the square conducting plate was numerically obtained when the plane wave is incident. The current distribution on the conducting plate in the case of spherical wave incidence is expressed by the integration of induced current due to the plane wave incidence. The scattered electric field was calculated and discussed. The electric field distribution near the conducting plate was measured and the existence of the dead zone was shown
