Dual polarized broadband dipole antenna feed with conical reflector for uGMRT

The Giant Metrewave Radio Telescope (GMRT) is an international facility for Radio Astronomy, operational since 2002. It consists of 30 fully steerable prime focus feed parabolic antennas, each of 45 m. diameter, spread over an area with an effective radius of nearly 15 km, and covering frequencies in the range of 150 MHz to 1420 MHz. Though meant primarily as an aperture synthesis instrument, antenna arrays can be formed out of the 30 dishes, where separate sub-arrays can work on different frequency bands concurrently.
