Apparatus for measuring read range between RFID tag and reader

摘要

An apparatus measures a read range between a tag and a reader, which includes an electromagnetic anechoic chamber formed by connecting at least one unit cell in a row, the unit cell having an electromagnetic wave absorbent provided on an inner wall of each unit cell, an electromagnetic generation portion located at the unit cell at an end of the electromagnetic anechoic chamber and transmitting an electromagnetic wave through an antenna, and an electromagnetic measurement portion which measures a field strength of the electromagnetic wave transmitted from the electromagnetic generation portion using an electric field probe moving in the electromagnetic anechoic chamber.
