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…
Reactance Properties of Transmission Lines: Reactance Properties of Transmission Lines : Just as a suitable piece of transmission line may be used as a transformer, so other chosen transmission-line configurations…
Signal Generator in Electronic Instrumentation Articles: What is Signal Generator? A signal generator is a vital component in a test setup, and in electronic troubleshooting and development, whether on a…
Measurement of Power Articles: Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a…
