Abstract :
This work presents a low-cost, multi-beam antenna system, using a dielectric homogeneous lens as a focusing system. First, the design methodology of the antenna system, combining a homogeneous lens and its primary source, is described. Then, aberration phenomena generated by the lens are characterized. Finally, the primary source, used to correct these aberrations, is briefly described and measurement results of the global antenna system are presented.
