  • Abstract
    A novel phase shifter with defected ground structures (DGSs) for higher phase shift range is presented. The varactor diodes are mounted on DGSs of termination loads to control the large phase variation of the DGS at resonance. The experimental results of the proposed phase shifter show a 60/spl deg/ increase in maximum phase shift compared with that of a conventional one.
