Abstract

Observations of the red-shifted 21 cm line of atomic hydrogen offer the potential of opening a new window into this epoch of re-ionization (approx z = 6 – 30). Using CST Microwave Studio, modeled the Sinuous antenna from 50-250 MHz and compared it to Vivaldi antenna data obtained from Green Bank Observatory. At a height of 5 meters, above the dish, the Vivaldi data shows a strong agreement to the simulation. Sinuous antenna simulation data shows better overall performance and consistency in broader range of frequencies.
