Abstract
A wireless communication device including a system ground plane and a retractable antenna is provided. The system ground plane includes a feed point. When the retractable antenna is configured to be a first length, the wireless communication device transceives a first signal of a first bandwidth through the retractable antenna for a first radio frequency system. When the retractable antenna is configured to be a second length, the wireless communication device transceives the first signal and a second signal of a second bandwidth through the retractable antenna respectively for the first radio frequency system and the second radio frequency system. A center frequency of the first bandwidth range is substantially a first odd multiple of a reference frequency, and a center frequency of the second bandwidth range is substantially a second odd multiple of the reference frequency, and the first odd multiple is different to the second odd multiple.
