IE3D question
in using IE3D has anyone encountered problems with high q antennas?
for instance i've designed an annular antenna for gps app's say spaced 30 mils from ground plane and could not match ie3d results with actual measurements.
however if i redesign this antenna and space it say 100 mils the simulation results and actual measurements are quite close.
i donot do filter design however i would expect ie3d to have no problem handling high q designs due to zeland touting their filter simulation comparisons
any comments :?: :?:
