Abstract
A mobile device includes a hybrid antenna, a tunable circuit element, an RF (Radio Frequency) module, and a proximity sensor. The tunable circuit element provides an impedance value. The RF module generates RF power. The hybrid antenna is coupled through the tunable circuit element to the RF module. The proximity sensor is respectively coupled to the hybrid antenna, the tunable circuit element, and the RF module, and is configured to detect a specific distance between the hybrid antenna and a conductive element. The tunable circuit element and the RF module are operated according to relative information of the specific distance. If the specific distance is shorter than or equal to a first threshold distance, the RF module will reduce the RF power. If the specific distance is shorter than or equal to a second threshold distance, the tunable circuit element will change the impedance value.
