Geosynchronous Satellites have now become almost synonymous for communications satellites, because of their wide use in telecommunications due to the advantages over non-geosynchronous satellites. Because of the availability of a number of communication satellites over the geosynchronous arc, the communications between different parts of the world have become possible and affordable. The communication satellites have played a significant role in converting the world into a global village.
Different Frequency Range Distribution
This table might not provide all the necessary information for specific frequency range.
No hard and fast rule for opting an antenna for a particular frequency be there.
Many electrical factors (eg radiation efficiency, radiation pattern, maximum antenna gain, antenna impedance, frequency characteristics) and structural factors (eg shape, size, appearance, cost and other economic aspects) are to be taken into account.
