I have to simulate an antenna mounted on a car. I have the .CAD file
of the car and i have to draw myself the car in my antenna simulation
software (Feko). Because i can't draw all detail in a cad file, what i
want to know is depending of the frequency what are the revelant
detail of a car for an electromagnetic simulation?
Has anyone experienced in this or know a paper or a website talking
about this.

Please help me

Thx

The car is half of an asymmetric dipole. If you pursue that line of
thinking you'll find plenty of info. I'd model it as a ground plane with
drooping radials.
