1. A two-reflector offset type active antenna including a radio wave lens at a common focal point of first and second confocal reflectors, said lens having a collector with a collector first face that receives and picks up a concentrated and reflected beam derived from a beam emitted by an active source of the antenna towards said first reflector that encounters said beam, said collector being placed at the focus of the first reflector, and a primary array having an opposite face which re-emits, towards said second reflector, energy transmitted to a second face of said primary array from the collector first face by means of interconnections, said primary array being placed at the focus of said second reflector;

  • the primary array and the collector have plural sources, respectively, and the sources of the collector are respectively connected in a one-to-one geometrical configuration preserving relationship to respective ones of the sources of the primary array; and

    wherein the connection between each source of the collector and the corresponding source of the primary array includes a device providing fine phase adjustment.
