Reconfigurable antenna in mm-waves based on stratified lens and sources array

This paper deals with radiation pattern reconfigurable antenna in millimetre wave range. The innovative antenna system is based on an inhomogeneous HMFE lens (Half Maxwell Fish Eye) fed by sources array. The number of fed sources and the lens allow to both control the radiation pattern and to achieve a good efficiency. The global antenna permits to have beam shaping capability without phase shifters. Directive and sectorial radiation patterns can be obtained for both on-axis and off-axis configurations.
