Antenna subsystem is also an essential component of satellite system. Basically four main type of antennas are used:
these are
1.Monopoles and dipoles (wire antennas) which are mainly used in very high frequency and ultra high frequency to provide communication for TTC and M subsystem.
2. Horn antennas are mainly used at microwave frequencies. Horns are actually used as feeds for reflector.
3. Array antennas are actually phased array antennas which are used on satellites to form multiple beams from single aperture.
4. Reflector antennas are commonly used for earth station antennas and the most widely employed shape of it is the paraboloid with a feed placed at its focus.
