Abstract
An electromagnetic lens comprises two conductive sides between which there is arranged a cavity provided in its lateral portion with electromagnetic input/output coupling transitions to authorize a set of propagation laws between pairs of such inputs/outputs. Moreover, it comprises, substantially centered in the cavity, a substrate comprising a printed conductive patch of predetermined dimensions, so that the two conductive sides and the patch thus create a suspended three-plate strip line structure. The content of the cavity and the respective geometries of the cavity and of the conductive patch are chosen to comply with the propagation laws.
