Abstract :
Summary form only given. The talk deals the development of various types of antennas (from VHF to Ka Band frequencies) required for satellites and their respective ground stations spanning from omni directional antennas to directional, shaped beam, multiple beam antennas for satellite applications and highly directional antennas with high G/T, low sidelobes and good axial ratio for respective ground station antennas, for Indian space programme developed at ISRO Satellite Centre. The talk also outlines the efforts put up by the team in design of 32 mtr Indian Deep Space Network Antenna System involving dichroic mirrors and beam waveguide working at S and X Band with a provision to upgrade to Ka Band, for both up and down links.
