Optimal dielectric lens antennas with one or two homogeneous spherical layers

Abstract

We present the results of finding the extreme of accessible parameters of some lens antennas. Antennas were constructed on the base of the elementary structures-of a homogeneous one- or two-layer dielectric full-sphere with an optimum level of an exciting electromagnetic field on a rim. The computational and experimental results are given for some versions of real antennas.
