Abstract

An antenna includes a telescopic antenna and an antenna jacket, where the telescopic antenna extends from a side opening and an exposed part of the telescopic antenna is configured to rotate outside the antenna jacket. The antenna and any one or more antennas of a GPS antenna, a Wi-Fi antenna, and a diversity antenna form a combination antenna. The GPS antenna and other antennas are disposed in an area adjacent to the antenna jacket.
