Abstract: An electronic device is able to be embedded in a mobile device with a plurality of antennas. The antennas are electrically coupled to the electronic device through a connector. The electronic device includes a plurality of built-in antennas, a communication processor, a plurality of antenna switching circuits, and a control processor. The built-in antennas receive a wireless mobile communication signal. The communication processor calculates the reception strength of the wireless signal received by each of the built-in antennas or each of the antennas. Each of the antenna switching circuits is electrically coupled to one of the built-in antennas or one of the antennas according to a control signal. The control processor correspondingly outputs the control signal according to the reception strength of the wireless signal received by the built-in antenna and the antenna.
