EXAMPLE of NFC rectangular Antenna calculator:
INPUTS : a0 = 35 mm, b0 = 25 mm, w =0.2 mm, g = 0.2 mm, t =0.035 mm, N =3, E =1.65
OUTPUTS: Equivalent conductor diameter = 0.094,
Average length (aavg) = 33.82 mm
Average Width (bavg) = 23.83 mm
Inductance = 0.7127 µH

Mils to mm conversion

mils (input) :

mm (output):

mils input = 8
mm output = 0.2
Formula: 1 mm (millimeter) = 39.37 mils
