Import far field data from a Feko (.ffe), external ASCII or a CST far field scan
(.ffs) file 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.
Select one of the following:
To select far field data from a multi-frequency .ffe or .ffs file, select Use all
data blocks. The data is interpolated for use at the
operating frequency.
To select far field data at a specific frequency in a .ffe or .ffs file, select Use
specified data block number and enter the number of the
relevant data block.
To select a specific far field pattern in a .ffe or .dat file, select Use
specified point range1.
In the Start from point number field, specify
the line number of the first line to read.
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.
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.
1 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.
