Radome simulation with finite linear planar array

Hello

 

I have constructed a 18X18 linear planar array and it works fine.

However when I have added a radome to simulate this array behavior in presence of radome, the radome model has been multiplied by 18 as well.

How can I cancel this radome multiplication due to linear planar array definitions?

Attached the model files.

Thanks

    Hello Sem,

     

    The array feature in FEKO assumes that you are describing a unit element and thus the radome will also be duplicated. To simulate the array with the radome, you will have to create all the elements and excitations in the traditional way (not the array feature) and add the radome. If the radome is well separated from the array, model decomposition can be used (sample around the array and use that as an impressed source for the radome).
