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 comprising a shaped volume of dielectric material. According to the invention, the dielectric material comprises a granular agglomerate defined by a homogeneous or quasi-homogeneous distribution of granules of the same type and of small size with respect to the wavelength (λR, λT) 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 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.
