Abstract
A single-layer capacitive sensor comprises a user input region and a border region proximate to and outside of the user input region. The user input region includes a plurality of transmitter electrodes that are disposed within the user input region. The user input region also comprises a plurality of receiver electrodes disposed in a common stackup layer with the plurality of transmitter electrodes within the user input region such that the transmitter electrodes and the receiver electrodes make no crossings of one another in the common stackup layer or in any other layer within the user input region. The border region comprises a plurality of routing traces extending from the border region into the user input region to couple with the transmitter electrodes and the receiver electrodes. The border region also comprises a plurality of transmission traces disposed entirely within the border region.
