 29 Aug 2008 9:01 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 infinite ground plane to the finite one. The problem is to change to finite substrate, what should I do to change it without affecting my patch structure.
(It's a complex structure, and it will take more time if I need to draw it again)
If you don't mind, please give some your advice and suggestion.
Thank you indeed.
Andrew

Hi, 2cent:
It ist just 2 steps:
1. Define the dielectric type and remove the infinite subsrate in Basic Parameters.
2. Draw the shape of the finite dielectrics and define it as a finite dielectric call in Adv Edit->Define Finite Dielectric Call.
Regards.

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 frequency it just run fine (no error).
Please need your advice.
Thanks again,
Andrew

| It means no enough RAM available.
