1. circular plate antenna structure comprises:

  • Substrate has the perforation that runs through described substrate on it;

    Radiation sheet metal, it is connected on the surface of described substrate, offers the through hole of corresponding described perforation on it, has four angles on the described radiation sheet metal, has two symmetrical rescinded angles on any two diagonally opposing corners;

    Grounded metal sheet, it is connected in the bottom of described substrate, has thin slice on it, have the through hole of internal diameter on the described thin slice greater than described perforation, four sides at described thin slice are extended with a plurality of frequency reducing sheet metals, described frequency reducing sheet metal is covered on the side of described substrate, frequency reducing sheet metal on the described single side and the configuration of the frequency reducing sheet metal bevel on the side, opposite;

    AndThe signal feeding body, it passes described perforation, described through hole and described through hole, and is with described radiation sheet metal and is electrically connected, thereby forms signal feed-in point.
