How to create simultaneous port excitation in an array with several wire ports? FEKO 2023.1V

Hello,

I have a patch antenna 2 by 2 antenna array with four wire probes. The array has an infinite substrate and ground plane. I want to excite my multiple wire ports simultaneously so that I can get only one S11 curve for my 2 by 2 structure. How do I do that in FEKO?

Hi @sswh2,

When you create an antenna array using the Generate Antenna Array macro, Feko will give you an option to add S-parameter configuration. The same is applicable if an the array has an infinite substrate.

Hi @sswh2,

Maybe that will help you too.

Hi @sswh2,

@Shannon_Mistry mam I created the array using liner planar array from the left panel not using the macro, then I requested S paratemer configuration like you mentioned, but I saw my s parameter results and voltage source @11, voltage source@12, voltage source@13 ..like this giving me the same output plot like the S parameter plot . I have4 wire probe with 4 voltage sources at each element, then what does it mean by

voltage source1@1, 1@2 like this? why curves are same as s parameter?
