mustripweff (W, T, H)
% MUSTRIPWEFF Calculate the effective width of a microstrip line
%
% [Weff] = MUSTRIPWEFF (W, T, H)
% W is the width
% T is the thickness
% H is the height
%
function [Weff] = mustripweff (W, T, H)
if (W < 2*T),
error('Width is too thin');
end;
if (W > H/2/pi),
X = H;
else
X = 2*pi*W;
end;
Weff = W + T/pi*(1 + log(2*X/T));
