(TWTA, Klystrons) The signal is up-linked • Up converter from the Earth Station and received by many down • Modulator link centers in TV broad • Encoder casting via PDA(Personal • Multiplexer Digital Assistant). • IRD (Integrated Digital Earth Stations are widely used because of Receiver Decoder various advantages over analog.
TRANSMITTER Aid of antenna Produces radio wave Connect earth station to satellites Also connect television
ANTENNA & SATELLITE• An antenna (or aerial) is a transducer designed to transmit or receive electromagnetic waves. In other words, antennas convert electromagnetic waves into electrical currents and vice versa.
TYPES OF ANTENNA • Isotropic antenna (idealized) o Radiates power equally in all directions • Dipole antennas o Half-wave dipole antenna (or Hertz antenna) o Quarter-wave vertical antenna (or Marconi antenna) • Parabolic Dish / Reflective Antenna
