Abstract

What do we do when there is a need to model antennas and ground planes that have a geometry that is not planar? The accurate representation of our geometry can make a significant difference in the results, especially at higher frequencies. This paper describes how some powerful computer-aided design (CAD) tools can be developed to represent difficult non-planar antenna geometries that cannot always be drawn using the commercial EM modeling packages. These CAD tools not only become very useful design tools, but are also essential when it comes to designing the complicated geometry associated with spherical conformal antennas.
