Abstract
Abstract: The value of the horn antenna has been demonstrated in radio astronomy applications. The usage of horn antennas is restricted to professional applications solely due to expensive and complicated technology. A low-cost, simple-to-build horn antenna for 21cm H-line applications has been designed. It can be used for outreach and popularization efforts in science at the high school and college levels as well as for educational purposes. The horn has an aperture measuring 75.4 x 58.7 cm2 and a gain of roughly 20 dB. The LNA and BPF, SDR, and signal processing software make up the receiver system. The project can be advanced to test out the rotation curve discovery for applications such as charting our galaxy and interferometry.
