Problems with running a design of dual polarised multi-layer patch antenna

Hello Everyone,

I have implemented a dual polarised multilayer patch antenna in MATLAB.

I have been able to do the layout and everything. However, when I go to run the part with antenna pattern simulation, it gives an error.

Following is the error:

Index exceeds the number of array elements (1).

Error in antenna.Shape/fillFeatureHoleInMesh (line 861)

holeTriangles = [holeTriangles;ia(trhole.ConnectivityList)]; %#ok<AGROW>

Error in antenna.Shape/meshGenerator (line 722)

[p,t] = fillFeatureHoleInMesh(obj,p,t);

Error in antenna.Shape/parseNewMesherInputs (line 1111)

meshGenerator(obj,defaultHmax,defaultGrowthRate,defaultHmin,...

Error in antenna.Shape/mesh (line 797)

parseNewMesherInputs(obj,varargin{:});

Error in em.PCBStructures/runMeshGeneratorForEachLayer (line 44)

Error in pcbStack/meshGenerator (line 731)

[p_temp,t_temp,layer_heights] =

analyze(obj,frequency, parseobj.Results.ElementNumber, ...

Error in single_element_double_patch_antenna (line 66)

pattern(p,2.8e9);

I have attached the file too. Can anyone please help.

Swaroop

Hi Swaroop,

I understand that the error you are facing during the analysis on the dual polarised multilayer patch antenna is a known issue. This issue is already notified to the developing team.
