Abstract: It has been around 90 years since the discovery of the first radio waves. It was instrumental in the discovery of the stars, galaxies, quasars, pulsars and the cosmic background radiation. The worldwide radio facilities are mostly working on centimeter and decimeter parts of the radio regions after the interferometric baseline introduction, adoption of low-noise receivers’ configuration and the usage of advanced electronics. These techniques improved angular resolution, are cost effective and able to provide results in real-time. A very few radio antennas are working in low frequency radio regions.
