Antenna array Complex directional antenna consists of separate near-omnidirectional antennas (radiating elements) positioned in the space and driven by high-frequency … (from 'Glossary' of our website) |
All ArchivesResearching and optimizing the characteristics of lens antennas based of double-layer dielectric sphere ... refelections, dielectric losses, radiator directivity diagrams and transition layers are carried out. As an optimization criterion, the maximum value of amplifying ratio of the antenna is used. The maximum possible antenna characteristics are determined. The antenna characteristics based on double–layer homogenous sphere and Luneberg lens are compared.
