WebPropagation Paths. The radio frequency (RF) energy radiated by a transmitting antenna spreads out with distance. Therefore, radio waves strike the ionosphere at many different angles rather than a single angle. This can result in several different paths between a transmitter and a receiver, including the following: WebKalpana Patel, in Atmospheric Remote Sensing, 2024. Abstract. Earth’s ionosphere plays a crucial role in atmospheric electricity and is an interesting layer to study radio wave propagation or sky wave propagation in space.
