Are the return to ground points necessary? I ask this because looking at my Nexus S
(which also uses NFC), I can see it has an NFC antenna
on the back of the cover
but only TWO contacts. This leads me to believe this just uses TX1 and TX2 and ignores having to use a junction for ground. Why was this junction necessary in the Adafruit board?
FYI: I'm assuming the board has three contact points for the antenna denoted by TP4, TP5, and TP6 in the schematic...
