Was it necessary to post the same identical question twice? And then, when the second was closed, to re-open the duplicate? It is gone now.

I'm sorry, I didn't see I posted it twice and I didn't understand why it was closed .

Hi Alba,

I understand that you want to simulate a phased antenna array of 4 helix antennas using the Antenna Array Designer app.

When you create antenna arrays such as a uniform linear array (ULA), you can use antennas that are built into Phased Array System Toolbox.

Alternatively, you can use Antenna Toolbox antennas. Antenna Toolbox antennas provide realistic models of physical antennas. They are designed using method of moments.

Phased array antennas represent more idealized antennas that are useful for radar performance analysis and higher-level modelling. Some phased array antennas cannot be physically realized, such as the isotropic antenna but are still conceptually useful. You can build and analyse systems using both types of antennas in an identical manner.

You can refer to this example to understand how to construct a phased array with either Phased Array System Toolbox or Antenna Toolbox antennas: Using Antenna Toolbox with Phased Array Systems - MATLAB & Simulink (mathworks.com)

For more information about Antenna Array Designer App, you can refer to the following MATLAB documentation:

Design, visualize, and analyze arrays - MATLAB (mathworks.com)

I hope this helps you.
