3-D Modeling

Shapes and boolean operations, create antenna from shapes, conformal array of shapes and antennas

Create 2-D and 3-D geometric structures with material properties.

Use shapes with material properties and shape operations to create custom antenna. Define the feed for this arbitrary element and analyze the antenna or array using existing analysis functions. Use this custom antenna as an exciter for backing structures, an element in arrays, an element in the platform installed antenna, or an element in the plane wave excitation environment.

Create conformal array of metal, metal-dielectric, and dielectric shapes with antennas.
