Rectangular Waveguide Derivation: When the top and bottom walls are added to our parallel-plane waveguide, the result is the standard Rectangular Waveguide Derivation used in practice. The two new walls…
Rectangular Waveguides: Rectangular Waveguides - As we know already that the term skin effect indicated that the majority of the current flow (at very high frequencies) will occur mostly along…
Transmission Lines Articles: Fundamentals of Transmission Lines: Fundamentals of Transmission Lines (in the context of this book) are considered to be impedance-matching circuits designed to deliver power (RF) from the…
Extraterrestrial Communications: Extraterrestrial Communications : The most recent, and by far the fastest-growing, field of communications involves the use of various satellite relays, of which the first was launched in…
Tropospheric Scatter Propagation: Tropospheric Scatter Propagation is a means of beyond-the-horizon propagation for UHF signals. Tropospheric Scatter Propagation uses certain properties of the troposphere, the nearest portion of the atmosphere…
Space Waves: Space waves generally behave with merciful simplicity. They travel in (more or less) straight lines! However, since they depend on line-of-sight conditions, space waves are limited in their…
Sky Wave Propagation Frequency Range: Sky Wave Propagation Frequency Range is the ionosphere is the upper portion of the atmosphere, which absorbs large quantities of radiant energy from the sun,…
Uses of Ground Wave Propagation: Uses of Ground Wave Propagation along the surface of the earth and, as previously mentioned, must be vertically polarised to prevent short circuiting the electric…
