What are the fundamentals of radio wave propagation?
Radio waves can propagate from transmitter to receiver in four ways: through ground waves, sky waves, free space waves, and open field waves.
Ground waves exist only for vertical polarization, produced by vertical antennas, when the transmitting and receiving antennas are close to the surface of the earth.What are the 3 types of radio wave propagation?
Propagation of radio waves from a radiating transmitting antenna to the receiving antenna may take place in one of the following routes:
Ground waves or surface waves(up to 2MHz)Space wave or line of sight propagation(above 30MHz)Sky wave or ionospheric wave propagation(2MHzto30MHz)What are the basics of wave propagation?
The term wave propagation refers to the movement of waves.
All waves have frequency, amplitude, wavelength, and wave speed.
Wave propagation speed quantifies how fast the wave travels.- The EM waves of frequency from 2MHz to 30 MHz are reflected from the ionized upper layers of earth's atmosphere and hence the sky wave propagation.
