[olaney@xxxxxxxx]

Information on calculating the inductance of a rectangular loop can be
found at http://www.qsl.net/in3otd/rlsim.html
Make your loop out of 50 ohm microstrip.  Is this a 13.56 MHz
application?  If so, this is a near field design based on inductive
coupling, and all the formal antenna rigamarole can be ignored.
