Three designs of lens antennas with different lens types will be presented in this document. Such antennas with lenses can be used in real-life radar applications.
The first scenario assumes that the first illuminated surface of the lens (closer to the horn antenna) is hyperbolic while the second is flat (farther from the horn antenna). Similarly the remaining two scenarios are plane-convex and concave-convex.
All calculations are extremely efficient due to usage of Method of Moments (MoM) with unique higher order basis functions. The mesh elements can be 2 wavelengths large. WIPL-D built-in reflector object is customized to yield minimum simulation requirements for large apertures. The accuracy is controlled simply by adjusting number of segments. Simulations are prompt and results are tested for perfect convergence in only a few quick runs on a regular desktop or laptop. All the simulations last only a couple of seconds.
