Fig. 3.5 Effects of medium thickness on attenuation constant
Fig. 3.6 Influence of the plastic box’s thickness on the reading distance of RFID tag
measurement results are the ones after subtracting the noise. For convenience, we
choose the plastic box in 3 mm to test at different temperatures.
The reading distances of the tag are measured in 13 sets of temperature from 20 °C
to 80 °C. Then, a scatter diagram could be obtained by analyzing the measured data,
as shown in Fig. 3.7. The horizontal coordinate stands for test temperature and the
