1. A characteristics display apparatus for a wireless communication system having a reader and an RF tag, comprising:

  • a receiving block for receiving a transmitted signal from the reader and a modulated reflection signal from the RF tag at the same time as a wireless signal of the wireless communication system;

    a demodulation block for demodulating the received signal obtained at the receiving block; and

    a display block for displaying the processed results of the demodulation process, wherein the demodulation block conducts an orthogonal demodulation as the demodulation process and the display block provides signal points on an orthogonal coordinate display based on the processed results to display characteristics of the reflection modulation at the RF tag.
