Antennas are used as transition device between transmitter and free space.
Explanation:
Let's see how antennas work. Supposing I want to transmit a program to the world, first I will have to get the content ready. I will have to use microphones to record the required sounds, be it from nature or people's voice. Now this recorded program can be transmitted using a tall metal structure called an antenna. Antenna receives the electric signals to be transmitted, amplifies the signal and transmit it as electromagnetic radiation in the form of radio waves. These waves are partly electric and partly magnetic, and travel at the speed of light. These waves are then received by the receives and viewed by viewers.
