Abstract: A communication device is provided. The communication device comprises a metal back cover electrically connected to a system ground plane; a first antenna unit for generating a first operating frequency band of the communication device; a second antenna unit for generating a second operating frequency band of the communication device. The first antenna unit includes a first signal source electrically connected to a first metal frame via a first matching circuit. The second antenna unit includes a second signal source electrically connected to a second metal frame via a second matching circuit. The first matching circuit and the second matching circuit are configured to adjust bandwidths and frequency ratios of the first operating frequency band and the second operating frequency band.
