Abstract :
Paper describes a successful attempt to design numerically a two-dimensional shaped beam-switching dielectric lens antenna (DLA) with improved angular (scanning) characteristics. Reduction of the directivity degradation for off-axis feeds is achieved thanks to joint optimization of the lens shape and feeding array parameters. Synthesis of the antenna is performed using highly-efficient in-house software based on the Muller Boundary Integral Equations (MBIE) solver and Hybrid Genetic Algorithm (HGA) optimization routine.
