Hi, I'm a newbie in using IE3D. I have a problem on setting feed-network under ground plane.
In normal cases, the default setting of Ground is at Z = 0, and the substrate is depending on what material u use. i.e, RO4003 with thickness 0.8128mm, the ztop will be 0.8128mm. Then, the feed network will be located on 0.8128mm. This setting will not give any problems when adding lumped ports for RLC like Localized for MMIC.
Now, I want to make the feed at Z = 0, and Ground at Z = 0.8128. However, it gives "No infinite ground plane is underneath the localized port" when I add Localized for MMIC. How to solve this problem?
