Abstract: PROBLEM TO BE SOLVED: To provide recognition distance measuring equipment between a tag and a reader. SOLUTION: Recognition distance measuring equipment between a tag and a reader includes an electron wave anechoic chamber configured that at least one or more unit cells, having electromagnetic waves, absorber is provided in line on an inner wall, an electromagnetic wave generator, arranged in the cell of the one side end of the electron wave anechoic chamber to emit electromagnetic waves through an antenna; and an electromagnetic wave measure which measures the electric field strength of the electromagnetic waves, discharged from the electromagnetic wave generator through an electric field probe moving in the electron wave anechoic chamber. Consequently, the accurate electric field strength can be measured from the angle and the distance between the tag and the reader. COPYRIGHT: (C)2007,JPO&INPIT
