Abstract
A computing device includes a processing device that adjusts the operating parameters of one or more antennas based on capacitances detected at the one or more antennas. Capacitance sensors measure the capacitances detected at the one or more antennas and generate capacitance data. The processing device may adjust operating parameters of one or more antennas, such as frequency/band, radiation pattern, power, angle diversity, space diversity, etc., based on the capacitance data.

1-20. (canceled)
An apparatus, comprising:
- a radio-frequency component configured to generate radio-frequency signals and process radio-frequency signals;
- a capacitance sensing component configured to generate capacitance data based on signals received from a set of capacitance sensors, wherein the capacitance data indicates a set of capacitances or indicates a set of changes in capacitance detected for a set of respective antennas;
- and
- a processing component, coupled to the radio-frequency component and the capacitance sensing component, the processing component configured to compensate for attenuation caused by a proximate conductive object, wherein to compensate for the attenuation, the processing component is further configured to adjust a set of operating characteristics of a subset of the set of respective antennas based on the capacitance data, wherein the subset comprises fewer antennas than the set of respective antennas.
