考案の属する技術分野
本考案は、誘電体板の表面に複数の放射導体を
配列したプリントアレーアンテナに関する。[Detailed description of the invention] Technical field to which the invention pertains The present invention relates to a printed array antenna in which a plurality of radiating conductors are arranged on the surface of a dielectric plate.
従来技術
従来のプリントアレーアンテナは、市販の平面

列された放射導体では、指向方向に限界がある。Prior Art A conventional printed array antenna has a structure in which a conductor substrate is spread on one side of a commercially available flat printed circuit board, and a plurality of radiation conductors are arranged on the other side. It is easy to manufacture and has features such as low cost, light weight, and low profile. However, with radiation conductors arranged on a plane, there is a limit to the direction of directivity.

けるという方法がとられている。従つて、厚いプ
リント基板を使用して円筒面状のアレーアンテナ
を製作することができないため、使用周波数帯が
制限されることになる。 Therefore, attempts have been made to arrange elements in arbitrary shapes such as cylindrical, conical, and hemispherical shapes by taking advantage of the print antenna's ability to have a conformal configuration. For example, when radiating elements are arranged on a cylindrical surface, a method is used in which the radiating conductor elements are arrayed on a thin printed circuit board surface and then wound around the cylindrical surface. Therefore, since it is not possible to manufacture a cylindrical array antenna using a thick printed circuit board, the usable frequency band is limited.

いうプリントアレーアンテナの特徴が失われるこ
とになる。 When arranging the radiating elements in a hemispherical shape, it is not possible to wrap a thin etched flat substrate as described above, so the method is to adhere copper foil to both sides of a honeycomb of the desired shape, or as shown in Figure 2. As shown in FIG.
A method is used in which a (hexagonal) flat printed circuit board formed by etching is used as a unit, and a large number of these are laminated together to form a predetermined shape. Therefore, a hemispherical printed array antenna requires more manufacturing steps than a planar printed array antenna, is less mass-producible, and loses the features of the printed array antenna, such as simplicity and low cost.

That is, a conductor substrate 7 is integrally formed on one side (back side) of a dielectric plate 6 formed into a hemispherical shape, and a plurality of radiation conductor plates 2 are formed on the other side (front side) by etching. An array is formed. The dielectric plate 6 is formed by molding a dielectric material having a low dielectric constant, low dielectric loss tangent, and moldability. As the dielectric material, for example, one whose basic composition is bismaleimide triazine resin and silica powder can be used. This is a dielectric material with a relative dielectric constant of 4 or less and a dielectric loss tangent of 0.005 or less, which has a low dielectric constant and a low dielectric loss tangent, and has moldability, but it is of course possible to use other materials as the basic composition. It is. As shown in Figure B, two metal conductor foils 4
The metal conductor foil 4 on the front side of the double-sided copper-clad printed circuit board manufactured in one step is etched by sandwiching the moldable dielectric 5 and press-forming it with the mold 3. A radiation conductor plate 2 is thereby formed. The metal conductor foil 4 on the back side is used as a conductor substrate 7 as it is.
