ANTENNAS
This month we will be touching on computer simulation of antennas, and some of the pitfalls. Photo A is a picture of my copy of the EREPS, Engineer’s Refractive Effects Prediction System, a program in between ECHO 1 and MiniNEC. I remember having to sign for those 5-1/4-inch disks and being told it was a crime to discuss EREPS with non-U.S. citizens. Something I trust has been declassified in the last 32 years, but heck, I won’t talk about EREPS. Hihi!
Larson Simulators
The first computer program I know of that would really look at the gain, pattern, and impedance of an antenna was the Larson program. This simulator was originally done in FORTRAN and was designed around Yagi antennas.
