AntennaCAD is an advanced Graphical User Interface (GUI) for the Numerical Electromagnetics Code (NEC). Development of AntennaCAD was initiated in the early 1980's by General Motors to facilitate the use of NEC in analysis of vehicular antennas. The current version has been developed for Delphi by John Ross & Associates.


AntennaCAD runs under Windows 2000/XP. Windows Vista and Windows 7 are not supported. Some of the features of the program are listed below:

Licensing and Pricing

Now that Windows XP and the Visual Studio 6 are both EOL, we are no longer able to license and support his code. We continue to use it internally and on consulting projects however. Please contact Dr. Ross for additional details on how we can help solve your problems.
