Antenna model files I have created or adapted from others, and some which are as-is.
Migrating models and descriptions to GitHub.
Work in progress as I add and reformat the text into markdown format, fixup file names, and convert images from GIF to PNG.
Blog posts referencing some of these at https://lonneys-notebook.blogspot.com/search/label/Antenna_Models
Antenna modeling helps validate ideas, designs, and guides us to a solution. It also develops a much better understanding of how they work.
The models and information are provided as-is for self learning, and may contain errors or inaccuracies.
EZNEC (.ez)
- AutoEZ is an automation tool and optimizer used in conjunction with EZNEC (.weq).
- Arrayfeed (PDF Manual) is used with EZNEC to calculate coax line lengths (Christman) or L network values with 1/4 wave lines (current forcing) for two and four element phased arrays. Feed2EL is an Excel version of Arrayfeed with additional features. This post covers a practical example using Feed2EL and EZNEC.
- Advanced Antenna Modeling Book covers using EZNEC and AutoEZ from beginner to advanced users.
- EZNEC (now free, but no longer to supported or developed) is likely the better choice as it includes high accuracy ground model, wire insulation, transmission lines, L-Networks, Transformers and more. This provides the ability to model complete antenna systems as they would be built to see how a design behaves over the given bandwith. 4NEC2 I understand can do most of or all of this but is in my expierence is harder to use.
