A capacitive touch sensor panel, comprising: a plurality of sense lines formed on a single layer and supported on one side of a substrate; a plurality of drive lines formed on the same side of the substrate as the plurality of sense lines (306, 504), the plurality of drive lines formed from a plurality of polygonal areas, the plurality of sense lines (306, 504) and the plurality of drive lines forming an array of capacitive sensors; one or more ground guards (308, 416, 500, 606) formed adjacent to one or more of the sense lines for shunting electric field lines that would otherwise couple capacitance onto the sense lines; a plurality of connecting traces routed adjacent to the plurality of polygonal areas and formed on the same side of the substrate as the plurality of sense lines (306, 504), each connecting trace coupled to a different polygonal area from the plurality of polygonal areas, the one or more ground guards (308, 416, 500, 606) formed between one or more of the connecting traces and the one or more sense lines (306, 504) for shunting electric field lines from the connecting traces; bus lines connected to the connecting traces; the plurality of polygonal areas forming columns of polygonal areas; and characterised in that the plurality of connecting traces are connected to the plurality of polygonal areas and the bus lines so as to interleave the plurality of polygonal areas in that a first bus line is coupled to the polygonal area closest to the first bus line of a first column and to the polygonal area farthest from the first bus line of a second column, a second bus line is coupled to the polygonal area next closest to the first bus line of the first column and to the polygonal area next farthest from the first bus line of the second column, this coupling pattern repeating for the other bus lines, evidenced by a last bus line being coupled to the polygonal area farthest from to the first bus line of the first column and to the polygonal area next to the first bus line of the second column. a plurality of sense lines formed on a single layer and supported on one side of a substrate; a plurality of drive lines formed on the same side of the substrate as the plurality of sense lines (306, 504), the plurality of drive lines formed from a plurality of polygonal areas, the plurality of sense lines (306, 504) and the plurality of drive lines forming an array of capacitive sensors; one or more ground guards (308, 416, 500, 606) formed adjacent to one or more of the sense lines for shunting electric field lines that would otherwise couple capacitance onto the sense lines; a plurality of connecting traces routed adjacent to the plurality of polygonal areas and formed on the same side of the substrate as the plurality of sense lines (306, 504), each connecting trace coupled to a different polygonal area from the plurality of polygonal areas, the one or more ground guards (308, 416, 500, 606) formed between one or more of the connecting traces and the one or more sense lines (306, 504) for shunting electric field lines from the connecting traces; bus lines connected to the connecting traces; the plurality of polygonal areas forming columns of polygonal areas; and characterised in that the plurality of connecting traces are connected to the plurality of polygonal areas and the bus lines so as to interleave the plurality of polygonal areas in that a first bus line is coupled to the polygonal area closest to the first bus line of a first column and to the polygonal area farthest from the first bus line of a second column, a second bus line is coupled to the polygonal area next closest to the first bus line of the first column and to the polygonal area next farthest from the first bus line of the second column, this coupling pattern repeating for the other bus lines, evidenced by a last bus line being coupled to the polygonal area farthest from to the first bus line of the first column and to the polygonal area next to the first bus line of the second column.
