1. four-antenna mobile terminal system is characterized in that, described system contains:

  • Dielectric-slab, described dielectric-slab becomes rectangle, is used for circuit and the employed dielectric-slab of antenna part in the analog wireless communication system and mobile terminal;

    Metal ground is printed on the back side of described dielectric-slab, and this metal ground comprises and be used for the metal part of other parts except that antenna in the analog wireless communication system and mobile terminal, and is used for reducing mutual coupling between the antenna or adjusts the various ground branch structure of operating frequency of antenna;

    Ground branch structure in the described metal ground is for vertical symmetry axis symmetric arrays of described dielectric-slab;

    Four plane one pole antennas and corresponding microstrip feed line are printed on the front of described dielectric-slab;

    Described four plane one pole antennas are placed on four angles of dielectric-slab;

    Antenna element that distributes about in described four plane one pole antennas and feeder line thereof are for vertical symmetry axis symmetric arrays of described dielectric-slab;

    The antenna element that distributes up and down in described four plane one pole antennas adopts different main pole directions.
