defining a resistive strip in CST

Hi
I am designing a dielectric rod antenna which consist of a resistive strip with the profile shown in attached figure.
please help me to define a metal strip with given resistance profile in CST.
thanks

i came to know that commercial resistive strip of such profile is known as resistive card.
its available commercially but still i could not find how to define such profile resistive card in CST....
pls help

Hi
I am not sure you can define resistance of material as a function.
You could attempt to make such profile from a several blocks with different resistances connected together, this could give a good approximation.
