Abstract:
An input device includes a plurality of sensor electrodes, an antenna, and a shield trace disposed between at least some of the sensor electrodes and the antenna. The antenna may be coupled to a transceiver and may transmit and receive radio-frequency (RF) communication signals. The shield trace may reduce, at least in part, coupling of the RF communication signals from the antenna to the sensor electrodes. The plurality of sensor electrodes may determine a presence, and/or a motion associated with an input object.
