1. a planar monopole antenna is applicable to transmission one wireless signal, comprising:

  • One substrate;

    One grounded metal;

    One first sleeve shape structure (sleeve) is formed on this substrate and is electrically connected this grounded metal, and wherein this first sleeve shape structure is that a side by this grounded metal extends towards a first direction, and has one first length on this first direction;

    One second sleeve shape structure is formed on this substrate and is electrically connected this grounded metal, and wherein this second sleeve shape structure is to be extended towards this first direction by the two ends of this side, and has one second length on this first direction, and this side has one the 3rd length in addition;

    One radiant body is formed on this substrate and this first, second and tucks inside the sleeve between the shape structure, and this radiant body is strip, and has one the 4th length on this first direction, and wherein the 4th length is substantially equal to the summation of this first, second, third length;

    AndOne cable couples this radiant body, uses this wireless signal of conduction.
