Category - Far Field

These articles explain how to plot the far-field radiation patterns from an antenna or scattered by obstacles in various forms such as 2D charts, 3D radiation patterns, and polar diagrams. They also cover powers delivered, consumed, and radiated.

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...
Power Budget
Go to Results > Power Budget/RCS in the main menu to display the Power Budget dialog box, Fig. 1. The following list of parameters versus frequency will be shown...
Radar Cross Section
Go to Results > Power Budget/RCS in the main menu to display the Radar Cross Section dialog box, Fig. 1. The following list of parameters versus frequency will be shown when an incident field is used as the excitation...
Exporting the Far Field
The far field patterns and spectra can be tabulated and exported by going to the following commands in the Results menu...
Front-to-Rear and Front-to-Back Ratios: Applying Key Antenna Directivity Metrics
Understand the difference between Front-to-Rear (F/R) and Front-to-Back (F/B) ratios, key metrics for antenna directivity. Learn how to calculate and interpret these values using AN-SOF software. Improve your antenna designs with this essential knowledge.
