Greetings. According to the documentation phased.CustomAntennaElement can be used as an exciter for the cassegrain antenna object.
Here are the properties of my created CustomAntennaElement:
FrequencyVector: [6.8000e+09 6.9000e+09 7.0000e+09]
FrequencyResponse: [0 0 0]
PatternCoordinateSystem: 'phi-theta'
PhiAngles: [0 0.5000 1 1.5000 2 2.5000 3 3.5000 4 4.5000 5 5.5000 6 6.5000 7 7.5000 8 8.5000 9 9.5000 10 10.5000 11 11.5000 12 12.5000 13 13.5000 14 14.5000 15 15.5000 16 … ]
ThetaAngles: [0 0.5000 1 1.5000 2 2.5000 3 3.5000 4 4.5000 5 5.5000 6 6.5000 7 7.5000 8 8.5000 9 9.5000 10 10.5000 11 11.5000 12 12.5000 13 13.5000 14 14.5000 15 15.5000 16 … ]
SpecifyPolarizationPattern: false

I'm creating a new cassegrain object at line 18 using:
ant = cassegrain(Exciter=myCustomAntennaElement, Radius=[radius_primary radius_secondary],FocalLength=[primary_reflector_focal_length secondary_reflector_focal_length]);
And here are the errors I am receiving:
Error using phased.CustomAntennaElement/parenReference
Not enough input arguments. Expected 2 (in addition to System object), got 1.
Error in em.MeshGeometry/checkObjectClass
Error in em.ParabolicAntenna/set.Exciter (line 44)
checkObjectClass(obj,propVal)
Error in em.ParabolicAntenna (line 34)
obj.Exciter = aExciter;
Error in cassegrain (line 101)
obj = obj@em.ParabolicAntenna(parserObj.Results.Exciter,...
Error in CassegrainAntenna (line 18)
It breaks inside ParabolicAntenna.set.Exciter function (I will provide only the part of it) at the checkObjectClass method:
function set.Exciter(obj,propVal)
checkObjectClass(obj,propVal)
objClass = class(propVal);
excludelist = {'cavity'...
Here propVal equals the CustomAntennaElement provided earlier, and obj equals the cassegrain object:
cassegrain with properties:
Will gladly appreciate any helpful suggestions.
