Element Gain Pattern

I have simulated a linear array in FEKO and have observed the total radiated E-field pattern in POSTFEKO.

 

I wanted to know how can I obtain (and hence extract) the gain pattern of individual elements in a linear array antenna? Please suggest.

    Hi Bidish

     

    Usually you would have to excite just the one element you want the pattern for and load all the other elements with typically 50 Ohm.

    You can do it in a single model by using multiple configurations in CADFEKO.

     

    You can view a video of how multiple configurations are setup here:

    Thank you very much Mel. I have tried this and I can see the gain pattern of a particular element in an array when all the other elements are terminated with matched loads (say 50 ohm).

    But is it possible to obtain the active element gain pattern (i.e., the gain pattern of a particular element when all the other elements in the array are excited)?

    Hi @Bidisha Barman,

     

    Maybe you can make use of the 'Scope' in the far field request. There you can select which faces/wires are taken into account for the far-field calculation. You could for example select only those faces from the one element you're interested in.

    Thank you Torben. It is working.
