Simulated radiation features of a C-band phased-array-feed located at the Sardinia Radio Telescope primary focus

Paola Di Ninni, R. Nesti, Paolo Maxia, Alessandro Navarrini et autres

This study focuses on the radiation performance of a system composed of a room-temperature C-band Phased Array Feed (PAF) illuminating the 64-m diameter Sardinia Radio Telescope (SRT) main reflector from its primary focus (f/D=0.328). The PAF, a square array with 8x8 dual-polarized …
