Abstract :
This paper deals with feed array suitable to SAR mission employing large reflector antennas (~10-15m projected diameter). The feed array, in patch technology, is specifically designed to accomplish various mission operative modes in a modular way. A key feature of such feedarray is the capability of cancelling the high cross-polar components at secondary level, intrinsically generated by large reflector with short F/D ratio, allowing the SAR instrument operating in dual linear polarization.
