Abstract
A device includes a capacitive touch sensor having a copper trace defining a capacitive electrode. The copper trace has a saw-tooth configuration. An ultra-high frequency (UHF) antenna is provided. A metal ground plane integrates the capacitive touch sensor with the UHF antenna. The saw-tooth copper trace aids in reducing interference with the UHF antenna.
