Title:
HORN REFLECTOR ANTENNA
Document Type and Number:
Japanese Patent JPS5698904
Kind Code:
A
Abstract:
The present invention relates to a method for reducing the weather cover-induced reflection sidelobes associated with horn reflector antenna arrangements. More particularly, the present invention consists of attaching the weather cover (26) to curved forms (21,23) placed in the antenna aperture, where the forms are shaped to contour the weather cover into a cylindrical paraboloid form, this form being capable of focusing the reflections from the weather cover onto a line inside the antenna arrangement. By covering this line inside the antenna with microwave absorbing material, (36) the focused weather cover reflections may be absorbed, thereby significantly reducing the sidelobes caused by the presence of the weather cover.
