Paper describes designing procedure of dielectric lens antennas (DLA) for multibeam applications. Two configurations of DLAs are considered, namely: two-shell circularly-layered lens excited by a horn antenna and shaped homogeneous flat-bottom lens excited by an array of printed feeds. Synthesis of the antennas is carried out in the 2-D formulation using highly-efficient in-house softwares based on...
The paper describes a procedure for designing two-shell circularly-layered dielectric lens antennas (DLA) with radiation characteristics compatible with conventional multi-layer uniformly-layered Luneburg lens (LL) antennas. It is demonstrated that a two-shell lens with the favorable collimating capabilities can be designed using standard low-permittivity materials provided the proper selection of...
