APPARATUS FOR MEASURING READ RANGE BETWEEN RFID TAG AND READER
First Claim
1. An apparatus for measuring a read range between a tag and a reader, the apparatus comprising:
- an electromagnetic anechoic chamber comprising;
two end unit cells, each end unit cell having an inner wall with an opening;
wherein an electromagnetic wave absorbent is provided on the inner wall, and wherein the opening of each end cell is capable of being joined to an opening of the other end unit cell;
an electromagnetic generation portion located at one end unit cell 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.
