Microstrip antenna

Abstract

Abstract PURPOSE:To improve turbulence in an electric field and to suppress a high-order mode, by sandwiching and superposing one or more dielectric plates on which a conductor plate is printed other than the conductor plate print-formed so as to be resonated to two frequencies between an upper and a lower microstrip antennas. CONSTITUTION:To realize the making two resonance into a wide band area, the number of dielectric plate is increased. In such a case, the dielectric plates 14-17 on which circular conductor plates 4-6 and 11 with diameters smaller than that of a circular conductor plate 1 printed so as to be resonated to two frequencies on the dielectric plate 13 are print-formed are inserted and superposed between the dielectric plates of the upper and lower side microstrip antennas I and II. And the circular conductor plates of the lower plane at an upper side and the upper plane at a lower side are fixed by a conductive coating material or by soldering so as to be fitted with other, or confronted places are adhered by pressing so as to be adhered. In such a way, it is possible to improve the turbulence in the electric field, and to suppress the high-order mode.
