[embodiment]

Be first embodiment of the invention as shown in Figures 1 to 4, antenna modules 100 comprises antenna 1 and the insulation board 2 that fits together.

The antenna 1 three-dimensional antenna for being stamped to form by sheet metal, it comprises that grounding parts 11, an end are connected to the connecting portion 12 of grounding parts 11, vertically connect the Department of Radiation 13 of connecting portion 12 other ends and vertically connect grounding parts 11 and form the Parasitica 14 in gaps with connecting portion 12, Department of Radiation 13.Grounding parts 11 is roughly a rectangular metal sheet, and it has an edge 111.Connecting portion 12 extends to the upper edge zigzag path from the edge 111 of grounding parts 11.Department of Radiation 13 extends and comprises second one 132 that the free terminal that is positioned at first one 131 on the longitudinally and is positioned at Department of Radiation 13 extends along zigzag path from the upper end edge of connecting portion 12 and grounding parts 11 parallel directions.Parasitica 14 is half " worker " shape and comprises the edge 111 that connects grounding parts 11 and be positioned at bottom 141 on the longitudinally, vertically connect the middle part 142 of bottom 141 and the top 143 identical with the bearing of trend of Department of Radiation 13.Antenna 1 also comprises the L shaped support portion 15 of extending from the edge 111 of grounding parts 11.Described connecting portion 12, Department of Radiation 13, Parasitica 14 and support portion 15 are in the same plane and vertical with plane, grounding parts 11 place, and connecting portion 12, Department of Radiation 13, Parasitica 14 and support portion 15 are equipped with manhole 16.

Insulation board 2 is made by insulating material such as PC (Merlon), Myclar (wheat is drawn), Nylon (nylon) etc., it comprises first surface 21, second surface 22 and some other surfaces (not indicating), first surface 21 is broader rectangle, and second surface 22 is narrower and vertically connect first surface 21.The some projections 231 that also are provided with some breach 23 on the insulation board 2 and extend out from breach 23, projection 231 is corresponding with the through hole 16 of antenna 1.

During assembling, insulation board 2 is assembled in antenna 1, the projection 231 of insulation board 2 passes the through hole 16 of antenna 1, the connecting portion 12 of antenna 1, Department of Radiation 13, Parasitica 14 and support portion 15 are posted by the first surface 21 of insulation board 2, grounding parts 11 is posted by the second surface 22 of insulation board 2, melt projection 231 by the high temperature instrument then and block through hole 16, make antenna 1 with insulation board 2 firm being retained on.

As Fig. 5, Figure 6 shows that second embodiment of the invention, antenna modules 200 comprises assembling antenna 3 and insulation board 4.
