Resonators and Waveguides Articles: 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…
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…
Quarter Wavelength Transmission Line: Sections of transmission lines that are exactly a Quarter Wavelength Transmission Line or Half Wavelength Transmission Line long have important impedance-transforming properties, and are often used…
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…
Antenna Characteristics: The following Antenna Characteristics isolated from surfaces which will alter or change their radiation patterns and efficiency. Current and Voltage Distribution: When an RF signal voltage is applied…
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 transfer could be achieved only…
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…
