APPRATUS FOR MEASUREMENT OF READ RANGE BETWEEN RFID TAG AND READER

摘要

An apparatus for measuring a recognition range between an RFID tag and a reader is provided to shorten the measuring time and improve reliability by accurately measuring the electric field strength at optional positions and providing a measuring analysis graph. An electromagnetic anechoic chamber includes at least one unit cell having an electromagnetic absorbing body(110) in a line. The electromagnetic absorbing body is installed on the inner wall of the electromagnetic absorbing body. An electromagnetic wave generation unit is positioned at the cell of one end of the electromagnetic anechoic chamber and generates electromagnetic waves through an antenna. An electromagnetic wave measurement unit measures the electric field strength of the electromagnetic wave emitted from the electromagnetic wave generation unit by a field probe(280).
