Cavity Resonators: A cavity resonators is a piece of waveguide closed off at both ends with metallic planes. Where propagation in the longitudinal direction took place in the waveguide, standing…
Impedance Matching and Tuning in Waveguide: We know that suitably chosen series or parallel pieces of transmission line had properties which made them useful for providing resistive or reactive impedances.…
Waveguide Junctions: When it is required to combine two or more signals (or split a signal into two or more parts) in a waveguide system, some form of multiple junction…
Methods of Exciting Waveguides: In order to launch a particular mode in a Methods of Exciting Waveguides, some arrangement or combination of one of more antennas is generally used. However,…
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…
Parallel Plane Waveguide: Parallel Plane Waveguide - As we know already in connection with transmission lines, that reflections and standing waves are produced if a line is terminated in a…
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…
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…
