Communication device

Abstract

A communication device includes a first sensing electrode, a sensing and processing unit, a radio frequency unit, a first antenna and a second antenna. The radio frequency unit, the first antenna and the second antenna are coupled to the sensing and processing unit. The radio frequency unit is configured to generate a radio frequency signal. The first sensing electrode is configured to sense a first capacitance when an object approaches the communication device. The sensing and processing unit is configured to generate a relative position signal of the object and the communication device according to the first capacitance. The sensing and processing unit is further configured to control one of the first antenna and the second antenna to send the radio frequency signal according to the relative position signal.
