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.

Abstract: A mobile communication terminal, a method for optimizing wireless performance, a device and storage medium thereof are provided. The method comprises: when sensing the terminal is located proximate to the head of a user, determining a band and channel that are currently used by the terminal according to the intensity of a received signal; adjusting a compensation network in an antenna circuit according to the band and channel, to weaken the transmission performance of an antenna corresponding to the band while improving the antenna reception performance.

Abstract: Disclosed is an antenna device applied to a mobile terminal and mobile terminal. An antenna device applied to a mobile terminal comprises: a plurality of wide-frequency antennas, a plurality of switch arrays in the same number as the wide-frequency antennas, and a controller; the wide-frequency antennas are respectively disposed at different positions of the mobile terminal, each switch array among the switch arrays is connected with a different wide-frequency antenna among the wide-frequency antennas, the switch arrays are respectively connected with the controller; the controller is configured to determine an antenna among the four wide-frequency antennas which is available for a preset use scenario when the mobile terminal is in the preset use scenario; the switch array is configured to, according to control of the controller, turn on the antenna available for the preset use scenario among the wide-frequency antennas connected to the switch array with a radio frequency module.

Abstract: An antenna efficiency boosting device and a mobile terminal, wherein an antenna efficiency boosting device is configured for use in a mobile terminal, wherein the mobile terminal has a metallic housing, the metallic housing has at least one discontinuous position, the discontinuous position is for example a broken point, broken seam or broken slot, the antenna efficiency boosting device comprises at least one branch which is coupled to both ends of the discontinuous position and used to adjust the efficiency of the antenna of the mobile terminal.
