Abstract:
In receiving mode when an antenna gets signal from space, like satellite , it is known that there is a very little back ground noise emanating from sky, compared to noise generated by the warn 300 Kelvin earth during terrestrial communication . It is true that most of the noise received by an antenna pointed at the sky is earth's noise arriving through feed spill, which can be reduced by increasing edge taper.
