1. an antenna assembly is used among a multifrequency mobile phone and the worldwide positioning double-purpose system, comprises:

  • One base material, wherein this base material comprises a flat surfaces and arcuation surface;

    One first load point is positioned on this base material, in order to this system in the mobile phone radio-frequency module be connected;

    One first radiation metal wires is formed on this substrate surface, comprises;

    One high frequency path;

    Be formed on this flat surfaces;

    Wherein an end in this high frequency path is connected with this first load point, and this high frequency path is to be formed by connecting in regular turn on four line segments, is respectively the first, second, third and the 4th line segment;

    Wherein at the angle that has between this first line segment and this second line segment between 90 degree to 120 degree, at the angle that all has between this second line segment and the 3rd line segment and between the 3rd line segment and the 4th line segment between 45 degree to 60 degree;

    WithOne low frequency path is formed on this arcuation surface, and wherein an end in this low frequency path is connected with this first load point;

    One second load point is positioned on this base material, in order to this system in the global location radio-frequency module be connected;

    One second radiation metal wires is formed on this arcuation surface, and an end in the path of this second radiation metal wires is connected with this second load point;

    One short dot is positioned on this base material, in order to this system in earthing potential be connected;

    AndOne short circuit paths is formed on this flat surfaces, and wherein the two ends of this short circuit paths are connected with a turning point and this short dot of this second radiation metal thread path respectively.
