Waveguide Coupling

Waveguide Coupling: When waveguide pieces or components are joined together, the Waveguide Coupling is generally by means of some sort of flange. The function of such a flange is to…

Rectangular Waveguide Derivation

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…

Wideband Antenna Types

Wideband Antenna Types: It is often desirable to have an antenna capable of operating over a wide frequency range. This may occur because a number of widely spaced channels are…

Antennas in Electronic Communication Articles

Antennas in Electronic Communication Articles: Antenna Definition: The Antenna Definition is a quick review of impedance matching (basic transformer theory) and resonant circuits. It was pointed out that maximum power…

Antenna Coupling

Antenna Coupling: Antenna Coupling : Low and medium frequency antennas are the ones least likely to be of resonant effective height and are therefore the least likely to have purely…

Effects of Antenna Height

Effects of Antenna Height: At low and medium frequencies, where wavelengths are long, it often becomes impracticable to use an antenna of resonant length. The vertical antennas used at those…

Radiation Pattern of Antenna

Radiation Pattern of Antenna: The important terms and definitions used in connection with antennas and their Radiation Pattern of Antenna are Antenna Gain and Effective Radiated Power: Certain types of…

Sky Wave Propagation Frequency Range

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,…
