Abstract
A mobile device includes a hybrid antenna, an adjustable circuit component, a radio frequency module, and a proximity sensor. The hybrid antenna has a dual function of a radiator and a sense plate. The adjustable circuit component can provide an impedance value. The radio frequency module can generate a radio frequency power. The hybrid antenna is coupled to the radio frequency module via the adjustable circuit component. The proximity sensor is coupled to the hybrid antenna, the adjustable circuit component, and the radio frequency module, respectively, and can be used to detect a specific distance between the hybrid antenna and a conductor component. The adjustable circuit component and the radio frequency module operate according to information related to the specific distance. If the specific distance is less than or equal to a first critical distance, the radio frequency module will reduce the radio frequency power. If the specific distance is less than or equal to a second critical distance, the adjustable circuit component will change the impedance value.
