Title:
EXPANSION TYPE REFLECTOR ANTENNA
Document Type and Number:
Japanese Patent JP2013201480
Kind Code:
A
Abstract:
To solve the problem that a reflector antenna folded in divisions of a plurality of reflector surfaces has a grating lobe corresponding to intervals of cutting portions of the divisions of the reflector surfaces and generation of interference and a false image may be caused.
An expansion reflector antenna is constituted so that a plurality of reflector surfaces parted by polygonal cutting portions comprising a plurality of straight lines or a plurality of smooth curved lines are folded, and then a grating lobe generated at a cutting portion is lowered in peak value to suppress unwanted waves, thereby suppressing generation of interference and a false image.
