Abstract
A tunable delay line for radiofrequency applications includes a waveguide and a dielectric perturbing member that is displaceable relative to the waveguide for varying the delay imparted by the line. The waveguide is a ridge waveguide and the perturbing member is arranged parallel to a longitudinal end surface of the ridge and is movable in the ridge plane, toward and away from the ridge end surface, or in a direction transversal to the ridge.

- 26. A continuously tunable delay line, comprising a waveguide and a dielectric perturbing member that is continuously displaceable relative to the waveguide by displacement driving units for varying the delay imparted by the delay line, said waveguide comprising a ridge waveguide with a longitudinally extending ridge, and said perturbing member being longitudinally arranged in the waveguide and being movable so as to vary the position of the perturbing member relative to a longitudinal end surface of the ridge.

47. A method for applying a continuous tunable delay to a signal by means of a waveguide comprising:
-
arranging a longitudinally extending ridge in said waveguide; arranging a dielectric perturbing member extending longitudinally to said ridge; and moving said perturbing member so as to vary a position of said perturbing member relative to a longitudinal end surface of the ridge. - View Dependent Claims (48, 49, 50)
