Recent advancements in radio observation have empowered astronomers to overcome obstacles presented by light pollution in urban areas. This current study delves into the utilization of karahi based antennas as a novel approach to observing celestial phenomena, with a specific focus on the emission of galactic neutral hydrogen. By capitalizing on radio waves’ exceptional ability to penetrate urban noise, in conjunction with advanced digital signal processing techniques and Software-Defined Radios (SDRs), precise measurements of galactic emissions can be attained. The paper provides comprehensive insights into the design, construction, and optimization of karahi antenna, elucidating engineering considerations and addressing practical challenges encountered throughout the project. Through a combination of simulation studies and field observations, the study showcases the potential of karahi antenna in radio astronomy applications, thereby offering a promising avenue for facilitating accessible astronomical research and promoting public engagement efforts.
