Quad-Ridge Flared Horn feed design and analysis for WBSPF in radio telescope
Paper i proceeding, 2017

A dual polarized Quad-Ridge Flared Horn (QRFH) feed for receiver systems is proposed and presented. The cryogenic 1.6-5.2 GHz feed system design is considered with emphasis on its application in future wideband radio telescope systems. A great deal of simulated and measured results are presented throughout this paper. Hence, the results showed that the proposed design achieved a low reflection coefficient, a main lobe with near-constant symmetrical beam width and an aperture efficiency higher than 64% across the bandwidth. Further developments needed to completely fulfill the requirements for these future wideband radio telescopes are also discussed. It is expected the present design could be a possible feed candidate that is suited for SKA radio telescopes, especially in SKA wideband single pixel feed (WBSPF) - advanced instrumentation programs (AIP) within the pre-construction phase.
