Satellite Communications — Satellite antenna
Information on Satellite antenna
The satellite antenna is a high-gain device for transmitting and receiving energy between the Earth station and the satellite. The antenna subsystem is a critical part of the spacecraft design. If the spacecraft antennas can be very large, we do not have to generate so much power on board to achieve the required power density at Earth-station antennas. Alternatively, for the same amount of on-board power, Earth station antennas can be smaller or a higher data rate can be achieved. Large antennas are difficult to mount, however, and cause structural problems as they need to be folded inside the launch vehicle and subsequently deployed in space.
