caculate the match capacitance for a given antenna

Author : xfpga Date : 2012-12-14 22:03:14

here is a reader'antenna, it is a LC circuit, so we have the formula:

so, for 2.5mH antenna, the match capacitance is : 648pF.
for 1mH, the match capacitance is : 1.62nF
for 680uH, the match capacitance is:2.38nF
