Active Reconfigurable Luneburg lens at 60GHz
Résumé
An active receiver antenna with beam scanning and beam shaping capability is described. This antenna is based on a plate inhomogeneous Luneburg lens fed by several waveguide sources. Firstly, a plate Luneburg lens is manufactured thru a new technological process allowing to change the refractive index of a single foam layer. The measured radiation patterns of this lens are compared with simulated ones at 60GHz. Secondly, the active antenna is detailed and measured radiation patterns demonstrate the beam reconfigurability of this antenna system.
