Abstract:
1. A delay element comprising: a first microstrip circuit comprising a first delayed travel path for a first signal from a first input port to a first output port, and a second microstrip circuit comprising a second delayed travel path for a second signal from a second input port to a second output port, said first and second microstrip circuits being arranged side-by-side in a facing relationship; and a perturber arranged between said first and second microstrip circuits, said perturber being displaceable toward and away from said first and second microstrip circuits along an axis perpendicular to said first and second microstrip circuits, whereby, when the distance of said perturber to one of said first and second microstrip circuits increases, the distance of said perturber to the other of said first and second microstrip circuits decreases and vice versa, the position of said perturber between said first and second microstrip circuits defining the difference between the time experienced by said first signal in travelling said first delayed travel path and the time experienced by said second signal in travelling said second delayed travel path.
