Radio Frequency Penetration - Electrical Engineering …

WebRefraction is the term used for the bending of radio waves. In outer space, with no atmosphere, radio waves propagate in straight lines. In the earth's troposphere, radio waves are bent, due to interactions with the bounded electrons in air molecules. Refraction is generally the most important effect on radar propagation, communications and ... WebFor every length of an antenna rod there is an optimized frequency for which the energy loses to the radio wave has a maximum in relation to the energy loses in the wave generator "circuit". Since for all frequencies the velocity of propagation (in vacuum) is the same there seems to be a simple relation between the rod length and the wavelength.
