ANTENNA.EXE | ANTENNA.EXE is a self unzipping DOS file containing WIRE, based on
some
of the original MiniNEC work. However, the changes were so drastic that it can no longer referred to it as a variation on MiniNEC. One feature that it has is that it can handle coaxial structures. Thus a coax can be analyzed as two wires of different radii. There is care required at the terminations since there is fringing capacitance since an actual end-cap has not been included. A paper covering the theory behind WIRE is also available for download. The plotting of current and patterns were designed to be rather straight

INSTYGO2.EXE | IYAGI GENETIC OPTIMIZER II -------------------------
YGO2 is a FREEWARE progarm. It may be freely copied and distributed, but ONLY as long as there is no cost to the recipient. Unlike the original release of YGO, this version allows the user to optimize the array at up to 15 different frequencies, and to specify a different driven element (if desired) at each frequency. Unexcited DEs are assumed to be terminated in the feed system characteristic imped- ance. YGO2 (YAGI GENETIC OPTIMIZER II) designs optimized Yagi antennas using one of the most recent and powerful techniques in applied electro- magnetics: a genetic algorithm. A genetic algorithm mimics natural sel- ection ("survival of the fittest") by creating generations of Yagi designs in which the best designs ("individuals") pass their design parameters ("genes") onto the next generation in such a way that better and better antennas are the result. GA optimizers can produce remarkable results not achievable with any other design technique. Genetic algorithms are superior to deterministic optimzers, and they are easily implemented on a PC. YGO2 is user-friendly and easy to run. All GA parameters are changed by editing a single set-up file. The user can specify popu- lation size, number of generations, antenna figure-of-merit, and all other parameters needed by the GA. The Yagi's performance is computed using NEC-2D, the state-of-the-art Numerical Electromagnetics Code (double precision) developed at Lawrence Livermore National Laboratory. When YGO2 has completed its optimization, the radiation pattern of the best antenna is plotted on screen. A separate plotting utility allows the user to view radiation patterns for other top designs on a generation- by-generation basis. One of the GA's most attractive features is that, instead of producing only one "best" design, it produces groups of designs that achieve similar performance. The designer can then select from these groups the Yagi that best meets the requirements. To install YGO2, copy the file INSTYGO2.EXE into the directory on your hard drive that you will use for YGO2. YGO2 files are created by executing INSTYGO2.EXE, which is a self-extracting EXE file. If you have a previous version of YGO2, simply overwrite all files of the same name. Be sure to check the README.TXT and YAGI_GA.TXT files for inform- ation on setting up a YGO2 run. The file NEC2INFO.TXT contains information on creating various size NEC-2D executables. Any changes to YGO2 will be described in the file UPDATE.TXT. Please read UPDATE.TXT if it is present. YGO2 is a DOS program that must be run under MS or PC DOS (ver.3.3 or higher), Compaq DOS (ver.3.31 or higher), or in a DOS window under MS Windows 3.0 or higher. YGO2 also requires an 80386/87 math coprocessor or higher CPU and about 1 MB of RAM (depending on the model size).

mynec4pc.zip | | | | NEC POST-PROCESSOR V. 2.1 | |
necpost2.bas is Nec-post-processor 2.1 developed by Agostino Rolando . The original file was necpostproc.bas by J. Boyer. I have taken Necpostproc.bas and nov.bas and mixed them together to display 2d - 3d radiation patterns and current distribution along the antenna . It works better with vertical radiators. This 2.1 version has eliminated some little bugs of earlier 2.0 . Note that ,in order to draw a true 3d radiation pattern, the antenna must be arranged as to have the feed point just in (0,0,0) coordinates. For yagi design, I found a good agreement with yagimax 3.0 program by Lew Gordon. Here you find : nec2pc.exe - nec2 for pc. Requires 486dx or better and as much memory as the number of segments you use for antenna's description. niv.exe - nec input viewer. Shows input structure descriptor files *.nec. You can evidentiate errors in designing your antenna before nec2pc processing. nov.exe - nec output viewer . Shows the distribution of currents along the antenna (*.out files). necpost2.exe - nec postprocessor . Shows radiation patterns and current distrib. for *.out files. A few sources examples are included. NOTE : To know how to compile input descriptor files, see Nec User's Guide in http://www.traveller.com/~richesop/nec/ , available in pdf format.

modelling metallic structures using a mesh of wires. It has powerful automatic
facilities for controlling the density of the mesh once the structure has
been broken down into a number of polygons. It can also be used as a general
NEC2 pre-processor. It was originally written by C.F. du Toit. Note that
the code uses its own data format, and unfortunately CANNOT import an existing
NEC2 model file, but it can of course export the model to a standard ASCII
file. A description of the pre-processor has been accepted for publication:

Computational Electromagnetic Society (ACES) Journal. (To appear.) A draft

This is a suite of programs written in BLT - an extension of TCL/TK - which are intended to assist in visualizing antennas. The package is intended to provide windows which show both antenna patterns and antenna configuration. An accompanying article in both LaTeX and PostScript form describes the process of designing a simple antenna using the system. The suite has been built under SCO 5.0.2 and SCO 5.0.4 (Free SCO), but should run under any system that can make the blt extension of tcl/tk work.

NEC.XLS Updated version VB1.10 (1/12/99) now online. NEC.XLS contains pages to handle the following topics: 1 INTRO
AN ANTENNA MODELLING PROGRAM, INTEGRATING THE CONVENIENCE of EXCEL with the POWER of NEC 2 ...for experienced EXCEL users, with access to adequate computing power. Release 1.07A ,1/7/98. This version, released privately, has a restricted number of prepared antenna design sheets. The Workbook is not locked, with the intention that users may add their own antenna design sheets. No charge is made, nor any responsibility accepted . WHAT NEC.XLS DOES The series of sheets in NEC.XLS allow you to automate most of the common tasks associated with using a NEC 2 engine for modelling antennas, and tabulating the results. This program automates your entire antenna assessment. It will step through up to three design variables at a time , with increments as selected. Having incremented chosen variables, a NEC INPUT DECK is automatically built. This is fed to a NEC 2 engine automatically. The Output file from the NEC engine is then read by EXCEL, and a summary of gain, F/B, and antenna input impedance is produced. If desired, a Thumbnail plot for each design is produced. Finally, a table of results is available, which is sorted by a Figure of Merit based on your weightings. The program thus loops away, building and summarising design changes within your set parameters. (contributed by the author Peter Ward <pward@net-tech.com.au> Bairnsdale, Victoria, Australia ) |
