Don¡¯t you feel that the Smith Chart is *far* away from the original posters
question about things for *beginners*? The original poster suggested
finding the resonate frequency of an antenna.
Smith charts show resonances, where plots crosses horizontal axis.
a quick skim read indicated no reference to what the x & y axes are,
which is something I have noticed with several descriptions of the Smith Chart.
Sad, because Smith chart simply plots S11 reactance vs resistance.
