	These are the measurement results for S11 and S21 of the tire connected to the matching circuits. The x-axis shows the frequency and the y-axis shows S11 and S21. [It is not recommended to explain what is obvious from the figure.]
	In this figure, the red line indicates s21 and the blue line shows s11.
	S21 is approximately -3 dB at 0.88 MHz. And the transmission loss of the matching circuit is approximately -1.3 dB.
	The transmission loss of the tire is estimated to be -1.7 dB from the above-mentioned results.
