Abstract:
A mobile device includes an antenna, an ESD (Electrostatic Discharge) protection component, a plurality of branches, and a switch. The antenna is configured to transmit and receive an RF (Radio Frequency) signal. The branches provide different inductances or different capacitances, and are respectively coupled to a ground voltage terminal. The switch is coupled through the ESD protection component to the antenna, and switches between the branches according to a control signal such that the antenna is capable of operating in a plurality of frequency intervals. The ESD protection component is configured to protect the switch from being damaged.
