Radio Antenna Design for Sky-Averaged 21cm Cosmology Experiments: The REACH Case
Radio Antenna Design for Sky-Averaged 21cm Cosmology Experiments: The REACH Case
Following the reported detection of an absorption profile associated with the 21[Formula: see text]cm sky-averaged signal from the Cosmic Dawn by the EDGES experiment in 2018, a number of experiments have been set up to verify this result. This paper discusses the design process used for global 21[Formula: see text]cm …
