ABSTRACT:
A radio tag evaluation system includes a transmission member providing a frequency signal to a radio tag. A transmitting antenna, which is placed on one side of the radio tag for transmiting the inquiry signal supplied from the transmission member. The radio tag is placed and supported around the center of an anechoic box. A receiving antenna is placed on the other side of the radio tag. A reception member is connected to the receiving antenna for analyzing a response signal. The transmitting antenna and the receiving antenna are placed orthogonally to each other, and the primary face of the radio tag is placed substantially at an angle of 45 degrees with respect to the transmitting antenna. The receiving antenna is unable to directly receive a transmission radio wave which has passed around the radio tag. Accordingly, a response signal emitted from the radio tag can be relatively strongly received.
