<P>PROBLEM TO BE SOLVED: To evaluate communication performance in regard to an RF tag evaluation apparatus when a relative position of an RF tag to an antenna varies. <P>SOLUTION: The RF tag evaluation apparatus includes an RF tag holder 1 holding the RF tag to be evaluated, being driven for linear translation in a predetermined moving plane; a test antenna 2 driven to rotate around an azimuth rotation axis (Ca) perpendicular to the RF tag moving plane, and to rotate around an elevation angle rotation axis (Ce) perpendicular to both the above azimuth rotation axis (Ca) and a moving direction line; and a memory 3 for storing communication quality between the test antenna 2 and the RF tag, using, as parameters, the position of the RF tag holder 1 and the rotation attitude of the test antenna 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
