i want to ask one question about four square antenna.
the reactance of the series element of the L network Xs=Zcoax^2 and the
reactance of the parallel element of the L network Xp=Zcoax^2/(X1-R1).Zcoax is
characteristic impedance of the quarter-wave feed lines.
why use the two formulas? and how to get the two formulas?
thanks!
