technology. Industries use RFID in different applications, frequency of operation. Following are the frequency ranges
such as personnel/vehicle access control, protection in for RFID tag such as low, high, passive, and active tags. The

industries, purchasing and manufacturing companies have
made RFID systems (Radio Frequency Identification) very
common. If a transponder is mounted in the neighborhood
of the leading plate without its own voltage, though in the
area of questions to the reader, the reader cannot obtain
the ID signal. The dead area in the RFID system is estimated
by the authors[1]. This paper examines the dead area of the
RFID scheme. At various angles is formulated the current
distribution developed on the square leading panel as
integration of the current distribution by flat waves.
Dispersed electrical field calculation and debate. Near the
lead plate is the electric field distribution and the dead area
is addressed [2].
