Abstract
A mobile communication device and a radiated power adjusting method thereof are provided. The mobile communication device includes an antenna, a signal measurement module, a proximity sensing module and a controlling module. The antenna receives a radio-frequency signal, and the signal measurement module is coupled to the antenna and measures a signal parameter of the radio-frequency signal. The proximity sensing module is switched between an activation mode and an original detection mode according to existence of an object, wherein a sensing conductor is configured adjacent to an adjusted antenna. The controlling module is coupled to the signal measurement module and the proximity sensing module, and the controlling module adjusts the radiated power of the adjusted antenna. When the signal parameter decreases more than a threshold value and the proximity sensing module is in the activation mode, the controlling module reduces the radiated power of the adjusted antenna.
