Golden Engineering
AN-SOF specializes in the modeling of wire antennas, including dipoles, monopoles, yagis, log-periodic arrays, helices, spirals, loops, horns, fractals and many other antenna types. The calculation method has been extended to also include single-layer microstrip patch antennas as well as printed circuit boards.
Data entry with AN-SOF is easy. To edit a wire just click on it and an edit box will come up with the relevant dimensions.
This is easier and quicker than searching through a spreadsheet to find a wire. Also, sources and loads can be seen graphically.
To visualize output data, you can have quite a collection of plotted images to compare and save as you run through a design. Electromagnetic fields, currents, voltages, input impedances, VSWR, consumed and radiated powers, gain, directivity, and far more parameters can be computed in a frequency sweep and plotted in 2D and 3D graphical representations.
AN-SOF is based on the Conformal Method of Moments (CMoM). Old MoM codes suffer from a number of drawbacks, such as: divergent input impedance, poor convergence for curved antennas (helices, loops, spirals), and singularities that appear when two parallel wires are close to each other or close to a lossy ground plane. With the CMoM we remove these limitations and obtain the following advantages:
