Antenna

The video tutorial explains the conversion of alternating electric currents into electromagnetic waves and vice versa. It discusses how the distribution of these waves is influenced by the design of antennas. High gain antennas are noted for their directionality, making them suitable for radar and space communication. In contrast, low gain antennas are effective in all directions, making them ideal for radio signals.

In what scenarios would a low gain antenna be preferred?

What are the practical applications of antennas in communication?
