ANTENNA PATTERN PLOTTER Version 1.21 Copyright (c) 1996 Atef Z. Elsherbeni and Clayborne D. Taylor, Jr. This program is a general EXECUTABLE ONLY 2-D Rectangular and Polar Pattern Plotter. The user interface for DOS makes the program easy to use. Since only the executable program is included, the user must first install the program using the following steps: 1. COPY A:\PLOTTER\*.* C:\PLOTTER\*.* 2. From the directory C:\PLOTTER type INSTALL Using these two commands installs the plotting routines of the program in the C:\PLOTTER directory. In addition, there are a few things the user should know in order to use the program effectively. 1. The program would handle the data and the output to the printer correctly if one always starts the program from the same directory in which it was installed. The data files can be located at different directories. 2. The format for a data file must contain 2 columns. Basically, the file is read through a FORTRAN free-format specification. If any errors occur during the read process, it is aborted with no plot given. The first column of the data represents the angle (in degrees) while the second column represents the quantity computed and plotted versus angle (i.e. field intensity, directivity, etc.). The maximum number of points that may be read is currently 2048 points. If the file is longer, only the first 2048 points will be plotted. The heading(s) of the two column data should be preceded by the # sign to allow the plotter to read the data correctly. If you use the computer programs "Antenna Theory: Analysis and Design" by Constantine A. Balanis, this has already been done; therefore neglect the comments. 3. When the plot window is "on top", a pull-down menu is accessible by holding the left mouse button down on the small box in the top left corner of the window. From there, the type of plot or the plot options may be selected. When editing the label text, greek characters are available by first typing the '\' key and follow by typing 'A'-'Z' or 'a'-'z'. A postscript file named 'FONTLIST.PS' containing the Greek font key equivalents may be printed for reference. Also note that the ~ symbol from the keyboard has been replaced by the degree symbol. 4. To use the plotting program, you can follow the steps that are outlined here: a. When you call the plotting program, the following options are displayed on the screen: CLEAR PLOT PLOT DATA FILE PRINTER SET UP QUIT b. If you want to view the plot but you do NOT want a hardcopy, select PLOT DATA FILE. c. Select the data file you want to plot. The screen shows some examples: sine.dat, cosine.dat, pattern.dat, ptest.dat which can be used for demonstration. By typing the path name, you can go to another directory and plot your own data. d. Then click OKAY. When you do this, the program automatically gives you a rectangular plot under Plot Window. e. If you click the the small box in the upper left corner of Plot Window, other options are displayed: POLAR PLOT RECTANGULAR PLOT PLOT OPTIONS PRINT f. Choose the one you want. Under PLOT OPTIONS, you can change the scale of the plot and of the formats of the scales. Choose the ones you want. For example, if you want to reproduce the normalized polar patterns (in dB) displayed throughout the book " Antenna Theory: Analysis and Design" by Constantine A. Balanis, choose POLAR PLOT and under PLOT OPTIONS select the following: min 'rho' -40 max 'rho' 0 'rho' tics 5 'rho' fmt F9.1 Click OKAY. The plot should now appear on the screen. g. You can switch between POLAR PLOT and RECTANGULAR options. Click CLEAR PLOT if you are done with this plot. You can repeat Steps 4b-4f for any other data file. h. If you want to place more than one pattern on the same plot, do NOT clear the first pattern using CLEAR PLOT in Step 4g. Instead repeat 4b-4g for the other data file that you want on the same plot. Both patterns should appear simultaneously on the screen, each with different line style. This process can be repeated for other data files. i. Click CLEAR PLOT in the main window to clear the plot(s). j. Click QUIT if you are finished with the plotting routine. 5. If you want a hardcopy of the plot: a. You MUST have a printer with postcript; if not, you can NOT get a hardcopy. b. Go to Step 4a and select PRINTER SET UP, and then do one of the following: i. If your computer is connected directly to the printer, you can use the LPT (i.e., LPT1, LPT2, LPT3 or LPT4) or COM (i.e., COM1, COM2, COM3 or COM4) options from the PRINTER SET UP of the plotting program; depending to which port the printer is connected. Skip to Step 5c. ii. If your computer is connected to your printer through a network, then you MUST use the FILE option under the PRINTER SET UP to create a postcript file and print later in Step 5d through DOS. For example, ARRAY1.PS c. Go and repeat Steps 4b-4h. d. Under PLOT WINDOW click the small box in the upper left corner, and select PRINT. e. Click CREAR PLOT in main window. f. Click QUIT in main window. g. Through DOS, go to the appropriate directory and recall the data you have created. h. Use the PRINT command in DOS, with the appropriate filename, to print the poscript file you have created. For example, PRINT ARRAY1.PS 6. Output is written to a file by default. Pressing any of the other port buttons will change the output to that port. Note that printers connected through the LPT and/or COM ports must be properly configured through DOS before running the program. Also note that color postscript is supported by selecting the 'COLOR' button. 7. If your data contains the angular dependence (column number 1) in radians, use the provided "conv" program to convert the first column from radians to degrees. Warnings: ======== If any problems occur during operation of this software, the CPU auto detection may not work for this hardware. To specify the hardware and software set-up, edit the batch file "plt.bat" according to the information in this batch file. A table along with instructions are listed in the batch file. If you start the program from a directory other than the one you installed it, expect unpredicted results.
