scaleEField

Scale electric and embedded electric field in pattern data

Since R2026a

Syntax

scaledAnt = scaleEField(mAnt)

Description

scaledAnt = scaleEField(mAnt) scales the electric and embedded electric fields in the measurdAntenna object created using the ffsReader function. You must scale the electric and embedded electric fields in the pattern data before integrating the data into RF Blockset.

Examples

Scale Electric Field in Imported FFS Data

This example does not provide sample data and the file names used are for illustration purpose. Use this workflow with your field data.

Change the working directory to the directory containing your FFS and S-parameter data files. Specify the file name and import the broadband pattern data for two antenna ports using the ffsReader function.

mAnt = ffsReader("broadband_source",PortList=[1:2],SparametersFile="sparameter_data.s8p")

broadband_source_[1].ffs

broadband_source_[2].ffs
