A method is presented on how to construct a conformal patch antenna in CADFEKO.
The conformal patch antenna consists of a finite dielectric substrate with a metallic (or
PEC face) on the top surface and a PEC ground plane at the bottom. The patch is fed with
a voltage source on a wire port. The patch antenna will be constructed as if attached to
a larger metallic cylinder with a specific radius.

and bottom view (right).
Dimensions
The patch antenna has the following dimensions:
Patch dimensions: 31.1807 mm x 46.748 mm
Ground plane: 50 mm x 80 mm
Substrate height: 2.87 mm
Relative permittivity: 2.2
Feed pin location is 8.9 mm from the centre of the model.
The patch is bent onto a cylinder of radius 40 mm.
Variable alpha is used for the angle subtended by the
ground plane at the centre of the cylinder.
Variable beta is used for the angle subtended by the
patch at the centre of the cylinder.
