External Antenna Pattern

The frequency of the antenna. The antenna design frequency is independent of the operational frequency of a transmitter, receiver, or radar. Changing the frequency of a transmitter, receiver, or radar does not update an embedded antenna's design frequency, or vice versa. The design frequency is solely used at antenna configuration time to compute the antenna size from its max gain or beamwidth settings. A mismatch between signal frequency and antenna design frequency typically causes performance degradation.

The path and name of the file that contains the antenna gain data.

If you are using an External antenna file with a symmetric pattern, you have the option of specifying the order of interpolation for the M^th order Lagrange interpolation algorithm. The value may range from 1 to 7, with 1 as the default if no value is specified or if the value is out of range.

Interpolation is used to calculate points between the values you specified in the input file for a symmetric pattern. 2D bivariable interpolation is used for 2D gain data on a regularly spaced grid, and the order of interpolation is linear.
