  • Abstract
    A time-delay phase shifter controlled by piezoelectric transducer (PET) is realized on a coplanar waveguide (CPW). The effective dielectric constant, propagation constant, etc., of the CPW are varied by the perturbation controlled by a PET. Compared to the perturbation on a microstrip line, published previously, the new CPW device provides 50% more phase shift.
