| Title of Invention | DEVICE FOR EMITTING AND/OR RECEIVING ELECTROMAGNETIC WAVES COMPRISING A LENS MADE OF A SHAPED VOLUME OF DIELECTRIC MATERIAL |
|---|---|
| Abstract | The invention relates to a device for emitting and/or receiving electromagnetic waves comprising a lens bringing a plurality of directions defined by the radiation space of the lens into correspondence with a plurality of focusing points defining a focusing surface of the lens, the lens lcomprising a shaped volume (7) of dielectric material. According to the invention, the dielectric , material comprises a granular agglomerate defined by a homogeneous or quasi-homogeneous distribution of granules (3) of the same type and of small size with respect to the wavelength of the electromagnetic waves to be received and/or emitted by the said device, the said granules being held under pressure in the said volume by holding means (2, 6) shaped according to the said volume. The invention also relates to a communications terminal comprising a device according to the invention. Particular application to devices for emitting and/or receiving signals in a telecommunications system with geostationary satellites, moving satellites or earth stations. |
