Re: NEC-LIST: Patch Antenna in NEC-Win

Farrukh,

I have had some success modeling the dielectric layer by placing many
lossy capacitors between the mesh and the ground plane.

Subject: NEC-LIST: Patch Antenna in NEC-Win

Hello all,
 Thanks for the previous helpful answers.
 I am modeling a patch antenna on a surface. I made a mesh (flat
surface)
and then placed it on the surface just above a height which was
equivalent
to the height of the substrate. However, this gave me erronous results.
 What am I doing wrong?
 Maybe, I have to model two meshes and place them on top of each other?
 I know I cannot model the dielectric so it will be kept as a free space
and
then adjust the answers manually later on. (Correct !??)
 Many Thanks,
Farrukh
