I am going to design a conical lens-horn-antenna to have a focused planar wave. I have the following questions:
1) How can I design it best?
2) biconvex or plano-convex Lens?
3) Spherical or hyperbolical Lens?
4) Do I need implicitly a corregated horn or It could work with a smooth-walled conical horn too?
5) How much should the minimum Fresnel-Number be to ensure the working the Lens in the region of the geometrical optics practically?
can anyone help me?
