    Change infinite to finite subtrate in IE3D

    Hi Jian, Thanks for the answer. OK, I've replaced the infinite substrate to the finite one. But when I want to process it (simulate), it appear an error message: "Dynamic allocation failed in allocating the matrix" What does it mean? What's the problem? Because when I run in in the lower...

    Change infinite to finite subtrate in IE3D

    Hi All, I've been using IE3D to make numerical calculation (simulation) on my MSA project. It's a 3 layers patch antenna. Until now, I've used the infinite ground plane and infinite substrate on IE3D. The next step, I would like to use finite ground plane and finite substrate. I've changed the...

    surface current in IE3D

    Hi jian, thanks for the reply, but sorry no mean to be rude. Do you mean it's the .cdd file? I've already try it but how that file gonna help me? (to figure out the TM mode or the circular polarization mode) Could it view the same way as the current distribution view? But separate only the...

    surface current in IE3D

    Hi All, I have some question on using IE3D. Hope someone could help me. 1. Can we see the real and imaginary parts individually of the surface current on IE3D. Because I need to figure out which TMmn mode at the given frequency of my antenna, and as far as I know by watching the quadrature...

    Need help using PlotSMITH

    plotsmith I really appreciate if someone could help me. I'M new in using this PlotSMITH software, the question is how I can create new project (the .p* file) form other software. In this case I would like to plot the result from IE3D. Thanks in advance. Andrew

    How to see the magnitude and the phase current while CP is generated using IE3D?

    Hi all, I'm new in microwave and antenna field... now I'm learning to design a circular polarize antenna... what I've learn so far is CP will generate for instance if there is a 2 component of the same magnitude but different 90 degrees in phase. The simple is by using two identical antenna...
