摘要: A unified proximity sensor including multiple physically separated radio antenna structure for mobile electronic devices that senses of a person to the antennae. Changes in capacitances antennae are detected based on low frequency signal output by single capacitance sensor. As human body approaches any antennae, this increases. Based increase capacitance, transmission powers signals emitted reduced.
