The MeerKAT radio telescope set in South Africa has been proposed as the instrument that will conduct a neutral hydrogen intensity mapping survey (HI IM) in single dish mode. A HI IM survey with MeerKAT will provide a great opportunity to study the composition and evolution of our universe. Measuring the cosmological HI signal is a challenging task due to the many systematics from the radio telescope. My research focus has been in providing a detailed analysis of the impact of the telescope primary beam on the contamination of data using realistic simulation of the HI IM observation pipeline.
