Simulation of Patch antenna with SMA connector

Post by gnumohan » Mon 21 Dec 2020, 14:50

Hi,

I am trying to use the Patch Antenna example program.

Is it possible to add the SMA connector along with Patch Antenna example program?

Thanks.
Mohan

If you get a good CAD model including all material parameters, it should be possible.
The question that remains is what you would gain from it?
I personally found that the simple lumped port is a good approximation of the inner conductor of an SMA connector and measurements tend to be in good agreement. You will never achieve a 100% approximation of a real device. An iterative process (between prototype and simulation) is usually the way to go.

Hi Thorsten,

Thank you very much for the inputs.

The problem trying to solve is the system level simulation. As advised, yes - agree. The 100% approximation of real device is not possible.

Let me give a try with FreeCAD and update the results.

Regards,
Mohan
