Abstract
The invention concerns a multilayer focusing spherical lens (,) adapted to be mounted in a transceive antenna device (,) of a terminal of a remote transceiver system and having a concentric focal sphere (S), the lens including a central layer (,) and a peripheral layer (,) having different dielectric constants, each dielectric constant value being determined so that the lens (,) focuses parallel microwave beams towards the focal sphere (S) concentric with the lens. A transceive antenna includes a lens of the above kind and a terminal for transmitting and receiving radio signals to and from at least two remote transceiver systems moving at different points in the field of view of the terminal, said terminal including an antenna of the above kind. The invention applies in particular to systems for transmitting data at high bit rates to and from a constellation of satellites, for public or private, civil or military use.
