Antenna Plots
Q: How do I display a plot of an antenna pattern?
A: You can plot antenna patterns in the TAP antenna library files.
Note that all values in this example are for demonstration purposes only. You should determine appropriate settings for your application.
Antenna patterns can be entered manually or imported from several different file formats.
Launch the Antenna form from the main TAP menu. Click Editors and then Antennas:
The HDAntennas form is displayed:
Click the lookup (“…”) button to select the TAP antenna library you want to use:
A list of the existing antenna library files is displayed. This will include the sample antennas included with TAP, as well as any other library files you have created by importing manufacturer’s antenna files.
Select the library you want and click Continue.
The libray may contain a number of antennas. Select the antenna you want and click the Close button.
The pattern will be loaded into the HDAntenna form, and a thumbnail of the azimuth and elevation plane patterns will be displayed.
Select the pattern you want to plot and click the button near the bottom of the form. The pattern will be plotted in more detail
You can adjust the scaling of the pattern by setting the minimum at the center of the polar plot.
Set the value you want to use to display the pattern.
The pattern will be redrawn with the new scaling. This may be useful in comparing the plotted pattern to the manufacturer’s published pattern.
You can set the number of radials drawn on the plot from the Antenna Plot menu.
The pattern is redrawn with the number of radials you selected.
