How to Obtain S parameters from far field source?

Juan Felipe Caicedo

Hello to everyone.

I'm trying to obtain the s parameters from two antena that are copuling, one I set it up as a far field source and the other one as a ideal RX. I do not have their geometries but im trying to obtain their S parameters in order to see the coupling.

Does anyone know if i need to define any extra element to set the s parameters? It's important to say that I don´t have a port due to the lack of geometry.

Should I define one? and to which geometry?

 

Thanks a lot

Hi @Juan Felipe Caicedo 

The coupling between 2 equivalent sources can be derived from the received power by the following equation in PostFeko:

Please refer to example B.3 Antenna Coupling Using an Equivalent Source and Ideal Receiving Antenna from the Feko Example Guide for a step-by-step tutorial.
