When I run the EHfields function like this:
[e,h] = EHfields(antenna_object,frequency)
The size of the output e is 3 * 441. Where 3 is the x,y and z component of the computed electric field.
When I run the function like this:
[eh,~]=EHfields(antenna_object,frequency, Polarization="H");
The size of the output eh is 1 * 441. Where 1 is the horizontal compoenent of the computed electric field.

My question is the 441. I am guessing that it is the index of the points evaluated as a unit sphere around the antenna. But in what ordered are they counted?
From Antenna Toolbox Coordinate Sytem it could be that it is counted from the azimuth angle from the positive x-axis to the vector’s orthogonal projection onto the xy plane, moving in the direction towards the y-axis and ranges from –180 and 180 degrees, and the elevation angle from the vector’s orthogonal projection on the xy plane toward the positive z-axis and ranges from –90 and 90 degrees.
But I don’t know for sure. I cannot find documentation clearifying how exactly are these points ordered, spaced and located. Perhaps a staff’s answer can be much helpful?
