The Cylinder Radio Telescope (CRT) is a new instrument designed specifically for 21-cm intensity mapping and the study of dark energy through the detection of Baryon Acoustic Oscillations. The 21-cm emission line of neutral hydrogen can be used to map large-scale structure in the universe. Mapping the 21-cm line promises new insights into galaxy formation, dark matter distribution and the dark energy that dominates the universe. We report on the design, fabrication and testing of feed antennas for the CRT prototype.
