Abstract
A radio-frequency (RF) device and a wireless communication device include a capacitive sensing unit capable of using a radiating element of an antenna to sensing an environment capacitance within a specified range, such that an RF signal processing device is capable of adjusting power of an RF signal accordingly, to prevent affecting a user. When the radiating element of the antenna includes a direct-current signal route to a ground terminal, the RF device and the wireless communication device further includes at least a capacitor for cutting off the direct-current signal route.
