Import far field data from a Feko file (.ffe), external ASCII file or a CST far field scan (.ffs) to create a far field data definition. Use the far field data when defining an equivalent source or receiving antenna.
The far field must be defined in spherical coordinates.
On the Construct tab, in the Define group, click the Field/current data icon. From the drop-down list
select Define far field data.
Select one of the following file types to import:
Load field data from Feko
Solver (*.ffe) file
Load field data from an external data
file
Loaf field data from a CST far field scan
(*.ffs)
In the File name field, browse to the file
location.
Far field patterns are typically frequency dependent and models with
radiation pattern sources usually have only a single solution frequency. If the
radiation pattern is calculated using a frequency sweep in Feko, the .ffe file contains multiple
patterns.
In the Start from point number field, specify where the
first line occurs in the file for the required pattern.
For example, if a far field pattern was calculated for 50 field directions
in a frequency sweep, the pattern for the third frequency starts at point number
101.
In the Number of theta points field, specify the number
of theta points used in the imported far field.
In the Number of phi points field, specify the number of
phi points used in the imported far field.
The data block number corresponds to the far field data at a specific
frequency.
In the Use data block number field, specify the data
block number that corresponds to the far field data at a specific
frequency.
In the Label field, specify a unique label for the far
field data.
Click Create to define the far field data and to
close the dialog.
