  • Patent number: 6429822
    Abstract: A microwave phase-shifter including a coupler in a waveguide form, at least one pair of phase-shifter cells, and a conductive strip positioned between each phase shifter cell and configured with a conductive plane to form a guided space where a wave cannot propagate. An incident wave entering a first input of the coupler is subdivided into two waves. Each of the waves are reflected on an elementary cell with identical phases to the incident wave and are recombined into a resultant phase-shifted wave prior to exiting the coupler by an output juxtaposed with the first input.

  • Patent number: 5153602
    Abstract: An antenna of the type comprising a set of distributor circuits made by symmetrical strip line circuit technology, distributing microwave energy to M radiating elements. The symmetrical strip line distribution circuits are placed so that they have at least one portion of their ground planes in common, thus reducing the bulk and weight of the antenna.
