Curved reflectors

Man-made or artificial satellites are equipped with curved reflectors in order to make the signals they receive stronger. Curved reflectors will increase the strength of a signal for any type of wave – whether that’s radio waves, microwaves, visible light, ultraviolet or even sound.

As the waves reach the curved reflector, or satellite dish, they are reflected by the curved dish and brought to a focus on an aerial. By concentrating the energy from all of the waves reflecting from the dish onto the aerial, the signal it receives is made much stronger.
