Description

【図面の簡単な説明】[Brief explanation of the drawing]

第１図は通常のカセグレンアンテナの基本的な構成を示
す図、第２図は副反射鏡端部における電波の散乱を表わ
す図、第３図、第４図、第５図はこの考案による副反射
鏡で、それぞれ斜視図、正面図、側面断面図を表わす。 図中１は一次放射器、２は主反射鏡、３は副反射鏡、４
は不要散乱波−５は散乱抑制リングである。なお図中同
一あるいは相当部分には同一符号を付して示しである。Figure 1 is a diagram showing the basic configuration of a conventional Cassegrain antenna, Figure 2 is a diagram showing the scattering of radio waves at the end of the sub-reflector, and Figures 3, 4, and 5 are diagrams showing the basic structure of a conventional Cassegrain antenna. A perspective view, a front view, and a side cross-sectional view are shown with a reflecting mirror, respectively. In the figure, 1 is the primary radiator, 2 is the main reflector, 3 is the sub-reflector, and 4
is an unnecessary scattered wave-5 is a scattering suppression ring. Note that the same or corresponding parts in the figures are indicated by the same reference numerals.

けたことを特徴とするカセグレンアンテナ。In a Cassegrain antenna that has a sub-reflector made of a hyperboloid of rotation or a curved surface approximating it, with a diameter of several wavelengths, a mirror is placed around the sub-reflector in the same direction as the sub-reflector in order to suppress unnecessary scattered waves from the end of the sub-reflector. 1. A Cassegrain antenna comprising a scattering suppression ring having a convex curved surface and having a width of 1/1 of the radius of the sub-reflector.
