    • 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.
    • 无线电标签评估系统包括向无线电标签提供频率信号的传输部件。 发射天线,放置在无线电标签的一侧,用于发送从传输构件提供的查询信号。 无线电标签被放置和支持在消声箱的中心周围。 接收天线放置在无线电标签的另一侧。 接收部件与接收天线连接,用于分析响应信号。 发射天线和接收天线彼此正交放置,并且无线电标签的主面相对于发射天线基本上以45度的角度放置。 接收天线不能直接接收已经通过无线电标签的传输电波。 因此,可以相对强烈地接收从无线标签发出的响应信号。
