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 6.2 TEST SYSTEM FOR NFC ANTENNA ATTACHED NEAR METALLIC SURFACE
The five sizes rectangular standard NFC antennas as well as the antennas with Ferrite are under
the detection distance test near metallic surface just as below.
