How can I implement custom antennas in MATLAB?

I am trying to model antennas using MATLAB, but I am not sure how to model the specific antenna that I have. I looked at the Antenna Designer App, but none of the form factors match my antenna - I am trying to model a spiral antenna that only has 1 arm, but both of the form factors in the App have 2 arms.

Is there a way for me to model my antenna?

From your description, I think that some of the tools in the Phased Array System Toolbox might be a better fit. This toolbox allows you to specify custom antenna elements.

To specify custom antenna elements in the Phased Array System Toolbox, you can use "phased.CustomAntennaElement" objects, in which you specify the response pattern of the desired antenna element (e.g. azimuth angles, elevation angles, magnitude pattern, and phase pattern). For an example of this, you can refer to the following documentation link:
