Scientific paper
Allen Telescope Array (ATA) is a radio telescope array applied in the project Phoenhix, US. The array will be operated from 0.5 to 11 GHz. A wide-band feed and an integrated MMIC front end will be equipped on each of 350 antennas in diameter of 6.1 m. A general introduction of the array and an initial analysis of performance and parameters of associated LPA feeds are presented in the paper. Preliminary simulation of the feed has been performed and indicated. The possibility of applying this kind of feed in the FAST project is discussed briefly at the end of the paper.
