draw and export omni directional antenna pattern for 5GHz wifi (vertical and horizontal)

I want to draw and export omni directional antenna pattern for 5GHz wifi ( vertical and horizontal) like the following images

how can I do this in Matlab?

I need the export format as 'ffs','HV',(phi and theta)(in the example.zip) Here is all of my matlab toolbox. (in MyMatlabToolBox.mat)

Hi Hong Cheng

In R2026a, Antenna Toolbox provides the capability to import radiation pattern data exported from CST. Using the ffsReader function, CST far-field source (.ffs) files can be imported into MATLAB and converted into a measured antenna object for further analysis and system-level simulations.

>> mAnt = ffsReader('ffsexample')

ffsexample.ffs


mAnt = 

  measuredAntenna with properties:
