Abstract
Devices and apparatuses are described. An apparatus may include radio frequency (RF) circuitry including a RF feed and a modem to transmit one or more signals via the RF feed. The apparatus may include an antenna structure including a first element and a second element. The apparatus may include an application processor coupled to the first element and the second element, where the application processor includes proximity sensing circuitry. The proximity sensing circuitry can measure a first capacitance value and a second capacitance value and the application processor can transmit a first signal of the one or more signals via the first element. The modem can determine whether an object is proximate to the first element and select the second element when the object is determined to be proximate to the second element.
