APPLICATION SPECIFICATION 5.0 MATCHING NETWORK DESRICPTION The matching network will depend on the selected NFC antenna and the NFC chipset. When customers use the NFC antenna, they should change the matching network according to the actual application environment. During the detection distance test, in order to get good detection distance, the NFC antennas have been well matched on the evaluation board with various capacitor’s value.

APPLICATION SPECIFICATION FIGURE 6.1.5 DETECTION DISTANCE FOR NFC ANTENNA WITH FERRITE AND TWISTED PAIR IN FREE SPACE 6.2 TEST SYSTEM FOR NFC ANTENNA ATTACHED NEAR METALLIC SURFACE Compared with test results for NFC antenna in free space, the only difference is the metal part, which was simulated by a PCB with copper. We evaluate the influence of the distance between the metallic surface and NFC antenna. FIGURE 6.
APPLICATION SPECIFICATION FIGURE 6.3 THE DISTANCE BETWEEN THE METALLIC SURFACE AND THE STANDARD NFC ANTENNA The below figure 6.4 to figure 6.17 show the detection distance between NFC antennas and the three RFID tags in different distances between NFC antenna and metallic surface. The effect of metal is evaluated with 4 different distances from the standard NFC antenna. The 4 distances are as follow: 0mm, 5mm, 15mm and free space (without metal part). From the Figure 6.4, Figure 6.6, Figure 6.8, Figure 6.
