Antenna Modeling & Design
Areas of application
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.
- design better antennas
- predict antenna performance
- tune for performance
- account for environment effects
- optimize a design using scripts
- get insight into the behavior of an antenna
- try many times before building the real model
- learn more about antennas and share our findings with colleagues. And to enjoy this exciting field!
AN-SOF can be used to...
Easy to use
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.
Cutting-edge simulations
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:
- Decreased number of calculations and increased accuracy of results.
- Decreased simulation time and computer memory usage, allowing us to model larger and more complex designs.
- Ability to simulate from extremely low frequencies (circuits at 60 Hz) to very high ones (microwave antennas).
