Hello, In **ie3d** first I am using the patch with Infinte **ground** plane. The results were quite good.But when I use the **finite** **ground** the results are not upto the mark.
Can any one suggest that how can I include the **finite** **ground** in microstrip antenna.
and after inserting it what is the (...)

In case of horizontally-**finite** **ground**plane, you can first define a metal type of 1-mm thickness, then assign the **finite** **ground**plane to this metal type. In case of in**finite** **ground**plane, there is no way to realize this in **ie3d** if the **ground**plane is highly (...)
