Can't use custom pcbstack antennas in arrays nor large platform analysis.

It is frustrating that custom antennas cannot be used with reflectors, in antenna arrays, and on large platforms. Are there plans to allow this in the future? Here is an error message when trying to analyze a pcbstack antenna on large platforms. Get similar output when using reflectors and arrays.

Error using installedAntenna/checkForDielectricMaterial

Element with dielectric materials is not supported for

installedAntenna.

Error in installedAntenna/set.Element (line 192)

checkForDielectricMaterial(obj, propVal);

Error in vivaldiProtoAnt (line 186)

ant.Element = vivaldi_Slot;

Hello Kirk,

I understand you are creating a customized object using 'pcbstack' for custom pcb stack antennas and you intend to use it with reflectors and antenna arrays.

MATLAB doesn’t support backing for ‘pcbStack’, but array is supported. As for the reflector aspect, it can be transformed into a ‘pcbStack’; however, please note that a ‘pcbStack’ cannot be designated as an excitor.

For more detailed information about 'pcbStack', I recommend referring to the following documentation and exploring the examples provided in the documentation:
