Mobile communications antenna device and a mobile communication terminal device

The present invention discloses a mobile communication antenna, the apparatus comprising: a monopole antenna placed on one side of the printed circuit board, and the distance from the center position of the printed circuit board is smaller than the threshold value, comprising: a first metal sheet , perpendicular to the printed circuit board, and turned on by the phase circuit and the feed point of the printed circuit board. The present invention also discloses a mobile communication terminal device. According to the present invention can achieve an ultra wide bandwidth antenna, so that the mobile communication terminal product, such as a fixed station and other possible to support more frequency bands; implements a fixed station and other mobile communication terminal device product high gain antenna, and improve the horizontal plane of the antenna FIG direction of roundness; realized common main antenna and GPS, Bluetooth antenna, and reduce the cost of the antenna.
