Satellite Antenna Diversity

Ka-band in satellite communications plays an increasing important role today. However, at higher frequencies, electromagnetic wave absorption increases. At Ka-band frequencies this can lead to service interruptions and performance degradation during rain fades. With high atmospheric losses, conventional fade margin approaches such as adaptive-waveform techniques or adaptive-power control techniques are not sufficient for compensation. For reliable and highly available operations, only site diversity configurations on the ground provide an adequate, fail safe solutions.
