Abstract- Present world is the world of communication, where radio wave is playing vital role and become essential part of life. We cannot work in 21st century without extensive use of radio wave, and now a days in any disaster, pandemic, and natural calamities, communication channels has to be established by using satellite, GEO, LEO or even drones. However, the future world will be unpredicted and more challenging. On the other hand, those waves are received by another antenna connected to a radio receiver, and that processes the received signal. Nowadays radio waves are extensively used in modern technology for fixed and mobile radio communication, radar and radio navigation systems, broadcasting, data link, communications satellites, wireless computer networks, command platform, military purpose and other applications.
