Definitions

  • the present invention provides a reflective termination coplanar waveguide phase shifter including a substrate, a tunable dielectric film having dielectric constant between 70 to 600, a tuning range of 20 to 60 %, and a loss tange between 0.008 to 0.03 at K and Ka bands, the tunable dielectric film being positions on a surface of the substrate, first and second open ended coplanar waveguide line positioned on a surface of the tunable dielectric film opposite the substrate, microstrip line for coupling a radio frequency signal to and from the first and second coplanar waveguide lines, and a connection for applying a control voltage to the tunable dielectric film.
  • the composition of the material is a barium strontium titanate (Ba x Sr 1-x TiO 3 , BSTO, where x is less than 1), or BSTO composites with a dielectric constant of 70 to 600, a tuning range FROM 20 to 60 %, and a loss tangent 0.008 to 0.03 at K and Ka bands.
  • the tunable dielectric layer may be a thin or thick film.
  • FIG. 13 is an exploded isometric view of an array 170 of 30 GHz coplanar waveguide phase shifters constructed in accordance with the present invention, for use in a phased array antenna.
  • a bias line plate 172 is used to cover the phase shifter array.
  • the electrodes on the dome of each phase shifter are soldered to the bias lines on the bias line plate through the holes 174, 176, 178 and 180.
  • the phase shifters are mounted in a holder 182 that includes a plurality of microstrip lines 184, 186, 188, 190, 192, 194, 196 and 198 for connecting the radio frequency input and output signals to the phase shifters.
  • the particular structures shown in FIG. 13, provide each phase shifter with its own protective housing.
  • the phase shifters are assembled and tested individually before being installed in the phased array antenna. This significantly improves yield of the antenna, which usually has tens to thousands phase shifters.
