Transmitting the same information over two or more distinct carrier frequencies.
Wave propagation refers to the way in which electromagnetic waves travel through a medium, such as air or space. There are several types of wave propagation, including: The final unit focuses on how radio waves

The textbook Antenna and Wave Propagation K.D. Prasad is a standard academic resource used for engineering courses. The book covers the principles governing how antennas convert electrical energy into radio waves and how these waves travel through different mediums.
