Method of designing parabolic offset antenna horn restrainer for suppression of sidelobe and antenna system using thereof

摘要

According to the present invention, an antenna system using a method of designing parabolic offset antenna horn support for suppressing a side lobe comprises: an offset parabolic antenna with a main surface of a reflector having a parabolic curved surface characteristic and a single focal point, and a height of the focal point is lower than a center height of the reflector; and a horn support disposed in a position designed to limit a level of a side lobe below a predetermined level outside a specified angular range, and the horn support is characterized by being disposed outside a horn support band avoidance reference area, and the offset parabolic curve can be prevented from being affected by the side lobe within the reference avoidance angle by using the avoidance area calculated in accordance with the focal point parameter, an offset height, and a reference avoidance angle, which are unique parameters of the surface.
