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.
Claims11
An electromagnetic lens device comprising:
- two conductive sidewalls defining a cavity arranged between said two conductive sidewalls;
- a substrate substantially centered in said cavity;
- a conductive patch of predetermined dimensions printed on said substrate and forming with said two conductive sidewalls a strip line with a suspended substrate;
- electromagnetic coupling transition inputs and outputs printed on said suspended substrate starting from said conductive patch, each of said electromagnetic coupling transition inputs forming with one of said electromagnetic coupling transition outputs an input/output pair;
- and
- a material arranged in said cavity, wherein geometries of said cavity, of said conductive patch and of said electromagnetic coupling transition inputs and outputs, and said material are chosen to comply with a set of predetermined propagation laws between said input/output pairs.
