Outlook for satellite communications at 20/30 GHz
Abstract
Regional and particularly national communications satellite systems can use the 20-30 GHz frequency band to advantage in areas where propagation conditions are not too unfavourable. The large assigned bandwidth at these frequencies will allow the increasing traffic requirements of the next few decades to be accommodated, while the smaller antenna dimensions compared with the 4/6 GHz and 11/14 GHz bands will be useful for generating small spot beams or contoured beams with fine detail. Interference problems on the ground are reduced, allowing ground stations to be sited nearer to cities, allowing savings in terrestrial communication links and increasing the possible traffic via satellite.
