IU was hoping you may be able to help me with the following formula:
LANT = 0.2 × Length × ln(Length/d - 1.6) × 10-9 × k
Where:
Length is the total antenna length in mm.
d is the trace width in mm.
k is a frequency correction factor.
LANT is the approximate antenna inductance in Henry's
This formula is taken from the following datasheet:
ln (LN, pronounced lon) is the logarithmic function where the base is e. When ln is written, it implies base e. When log is written it implies base 10. Something like log2 or log5 (the # are subscript), it means the base is 2 or 5 respectively.
Yes I've learned about logs, just it was about 15 years ago in Highschool, just wanted to make sure I remembered correctly....especially seeing as I couldn't find my 'log' bead on my abacus
You can buy scientific calculators fairly cheaply nowadays, failing that just use the calculator on your PC - all modern operating systems come with one.
