Tunable stripline devices |
摘要 |
A stripline device using at least one strip conductor and at least one ground plane separated therefrom by a dielectric substrate. The ground plane is caused to move relative to the strip conductor so as to change the propagation velocity of the stripline device. In a particular embodiment, a layer of piezoelectric material is positioned adjacent the ground plane and a voltage applied to the piezoelectric layer causes its dimensions to change and provide a changing air gap between the substrate and the ground plane to change the propagation velocity accordingly.
