Bandwidth enhancement for a touch sensor panel

A capacitive sensor, comprising:

• a sense electrode formed on one side of a substrate;
• a drive electrode formed on a same side of the substrate as the sense electrode and capacitively coupled to the drive electrode, the drive electrode configured for receiving one or more stimulation signals;
• and
• a bandwidth enhancement strip formed between the drive and sense electrode for providing a parallel path for capacitive coupling between the drive and sense electrode.

A method for enhancing the bandwidth of a capacitive touch sensor panel, comprising:

• forming a plurality of sense lines on one side of a substrate;
• forming a plurality of drive lines on a same side of the substrate as the plurality of sense lines;
• configuring the plurality of drive lines for receiving one or more stimulation signals;
• forming an array of capacitive sensors from the plurality of sense lines and the plurality of drive lines;
• and
• forming a bandwidth enhancement strip between one or more of the drive lines and one or more of the sense lines for increasing a capacitance between one or more of the capacitive sensors in response to a frequency increase of the one or more stimulation signals.
