ABSTRACT:
Edge terminations for polygonal impedance or resistance surfaces provide linearization of current flow to and/or from the surface through electrical connections at the vertices of the polygon. The edge terminations are constituted by a series of parallel ranks or rows of connective segments overlaid, inlaid or printed at each edge of the polygonal surface with the innermost row or rank being short straight segments and the length of each segment of the next innermost row, respectively, being longer. The central segment in each row or rank is electrically interconnected with the central segments in the other rows. A guard plane of conductive metal insulated from the impedance or resistance surface is also provided.
