1. A sliding phase shifter, comprising:
a fixed dielectric having first striplines to couple power into the sliding phase shifter; and
a sliding dielectric having second striplines electrically slidingly coupled to the first striplines, an amount of phase shift or delay of a signal being determine by an amount of overlap of the first striplines and the second striplines, the sliding dielectric having a first ground plane on at least part of one side of the sliding dielectric and having the second striplines on an opposite side of the sliding dielectric facing the fixed dielectric, and the sliding dielectric further comprising vias extending from the one side to the opposite side of the sliding dielectric, the vias encompassing at least a portion of a perimeter surrounding the first and second striplines.
