Tunable delay line using selectively connected grounding means

摘要

A tunable delay line system includes a stripline and a plurality of cross-over lines. The stripline defines a propagation delay characteristic. The plurality of cross-over lines are each spaced from and extend with an orientation that is nonparallel with the stripline. Each of the plurality of cross-over lines is configured to be selectively grounded to alter the propagation delay characteristic of the stripline.
