Description
Horn antenna has proved its worth in Radio Astronomy applications. Due to sophisticated technology & high cost, the use of horn antenna is limited to professional applications only. A cheap & easy to construct horn antenna for 21cm H-line applications is developed that can be used for education at the school & college level and also for scientific outreach & popularization activities within 7500 INR. The aperture of the horn is 75.4 x 58.7 cm2 and has a gain of about 20dB. The receiver system consists of a combination of LNA & BPF, SDR, and software to process the signals. The project can be taken forward to experiment with finding the rotation curve for mapping of our galaxy and interferometry applications.
