ABSTRACT:
A loopback conductor arrangement for a digitizer grid employs rotation sequencing of the conductors. The conductors in each of the X- and Y-directions are looped back and forth in a parallel, spaced relationship across the active grid area so as to provide a plurality of crossing conductor segments, with the positions of selected conductors (e.g., alternate conductors) in each successive loop shifting in sequential positions by a constant offset with respect to the other conductors in those loops.
