(3) Experimental results and analysis
The material of the test chamber is polyvinyl chloride, considering the influence
of the thickness of the test chamber on the reading performance of the RFID tag.
We tested the test chamber with thicknesses of 0.3, 0.5, 1, 2 and 3 mm at room
temperature, as shown in the Table 3.7.
