摘要：
An advanced dual-band antenna system suitable for broad-band satellites that is capable of providing higher EIRP, higher G/T, and improved copolar isolation among frequency reuse beams is presented. The antenna system employs a hybrid-cell frequency reuse scheme instead of conventional fixed cell reuse (4-cell or 7-cell) in order to efficiently use spectrum based on traffic demands. It is shown that the advanced antenna employing high-efficiency horns and shaped reflectors provides about 1.0 dB EIRP improvement, 2.0 dB G/T improvement, and 3.0 dB improvement in C/I when compared to conventional antennas.
