Over-range polyconical antenna with gradient dielectric lens

An omnidirectional in one plane polyconical antenna with a torroidal gradient dielectric anisotropic Mikaelian lens, which is made in the form of a set of parallel coaxial disks made of polystyrene of various thicknesses, is proposed and studied using numerical modeling. As a result of the study and optimization of parameters, it was shown that the optimized polyconical antenna with the lens is matched and provides high efficiency in the 40:1 frequency band. The results of numerical modeling are confirmed by the results of measurements of the manufactured antenna prototype.
