A voltage generator feeds a microstrip on a circuit board using an interior lumped port boundary condition. The model calculates the microstrip impedance and compares two terminations; a numerical port using boundary-mode analysis, and...
A radome minimizes losses and improves radiation characteristics of an antenna through its design. The structure can be optimized to minimize the transmission loss and also designed to improve radiation characteristics including antenna...
A fractal is a mathematical form showing self-repeating patterns. By virtue of its geometrical properties, a fractal structure can generate multiple resonances in RF applications. This antenna model uses a 3rd order Sierpinski triangle...
A conductive diaphragm, an iris, placed transverse to a waveguide aperture causes a discontinuity and generates shunt reactance. Bandpass frequency response can be achieved from cascaded cavity resonators combined with these reactive...
The optimization of components with respect to geometrical design parameters is a common task in microwave engineering. In this model the reflection coefficient of a waveguide structure is minimized, and the sensitivities of the real and...
In its simplest form, a magnetic dipole consists of a current carrying coil. Three such coils coupled together in an AC power circuit, constitute a radiating system. By changing the phases of the coils, you can alter the transmission...
A parallel wire transmission line is composed of two conducting wires in a dielectric such as air. The fields around such a transmission line are not directly confined by the conductors, and extend to infinity, although they drop off in...
The transmission of a TE10 wave through a 90 degree bend in a waveguide is modeled.
This is a model of a waveguide, a device used to conduct electromagnetic waves in the microwave range. The purpose is to calculate how well a TE10 wave propagates through a bend in a waveguide filled with a dielectric medium. This is...
The impedance of an antenna is an important parameter that determines how it behaves in transmitter circuits. Impedance matching and low reactive components are important to get reliable operation, which can be achieved either by proper...
