Dear all, 

 

Does any know how FEKO consider substrate layer and ground plane of microstrip patch antenna in CMA method? and what is the effects of substrate and ground plane on performance of the conducting surface?

Is not the methods for conducting surfaces? how consider substrate layer and ground plane?
 

yours sincerely.

    Hello @Saeedbarzegari

     

    Please check the Examples Guide example A-8, which will demonstrate the different approaches in FEKO how to model a finite substrate and ground vs. an infinite substrate and ground. This approach applies to general MoM simulation, but also CMA.

     

     

    The effect of the infinite approach will be determined by the actual size of your ground plane and substrate. But it is straightforward to try both approaches and compare results.

    Hello Peter Futter
    Thank you for your valuable answer.

    I am Writing a Matlab Code for analyzing a Patch antenna Using CMA. If you have any constructive point in this field, or any similar Matlab code  I will be Surprised?
