Summary:
This paper describes the design and development of a very wide band (> 3GHz), high gain lightweight (< 4kg) parabolic reflector antenna at Ku-band for synthetic aperture radar (SAR) applications. The antenna aperture dimension has been fixed to 0.7m x 0.2m to achieve a 3dB beam width of < 2° in azimuth and < 7° in elevation with a total gain of > 33dB over a 3GHz bandwidth with side lobe levels of -25dB. In order to achieve sum and difference patterns reflector is illuminated with multimode feed horn where feed higher order modes are utilized for producing difference beam.
