Types of Results
Commands to Display Results. The output data of a simulation can be listed in tables or displayed in graphs. All results are found under the Results menu...
The Results Tab
In the AN-SOF main window there is a Results tab, Fig. 1, where a table with the main results for a transmitting antenna is shown: input impedance, VSWR, directivity, gain and efficiency...
The Plots Tab
Select the Plots tab in the AN-SOF main window to visualize the plots of the main results for a transmitting antenna as a function of frequency.

Plotting 2D Far Field Patterns
The radiation pattern can be shown as a 2D rectangular plot by going to Results > Plot Far-Field Pattern > 2D Rectangular Plot in the main menu. This command displays the Radiation Pattern Cut dialog box...
Plotting 3D Far Field Patterns
The far-field can be shown as a 3D plot by going to Results > Plot Far-Field Pattern > 3D Plot in the main menu. This command executes the AN-3D Pattern application...
Plotting the Far Field Spectrum
Far-field frequency spectra are obtained when a simulation is performed by specifying a list of frequencies or a frequency sweep. For each frequency, the far-field is calculated at the several directions given by the zenith (Theta) and azimuth (Phi) angular ranges and...

Front-to-Rear and Front-to-Back Ratios
Two commonly used metrics for quantifying the directional properties of an antenna radiation pattern are the front-to-rear ratio, F/R, and the front-to-back ratio, F/B.
Plotting Near Field Patterns
Go to Results > Plot Near E-Field Pattern > 3D Plot in the main menu to plot the near electric field as a 3D graph with a color scale. This command executes the AN-3D Pattern application...
Plotting the Near Field Spectrum
Near-field frequency spectra are obtained when a simulation is performed by specifying a list of frequencies or a frequency sweep. For each frequency, the near-field is calculated at those points specified in...
