A capacitive sensor pad is co-located with (e.g., overlapping) an RF transmitter without causing significant degradation to the performance of the antenna. In one implementation, tuning the resistance per square in the capacitive sensor pad can provide effective sensor pad range and performance while providing making the capacitive sensor pad sufficiently transparent to radiofrequency waves to provide excellent antenna efficiency, despite the co-location of the capacitive sensor pad and the antenna.
