**ie3d microstrip**

Hello all

Just joined in.Nice to see such a huge collection of Microwave experts here.

I will keep my query short and ask for help of all here in this regard.

Consider a first iteration fractal design of a simple geometry to be used as a micro strip antenna..lets say koch,sierpinski,etc..now I want to iterate the design further and continue for 2 iterations and so on.Is there a way in which I could design such complex higher iterations on a software(..I read of a software called Ultra fractal in the forum) and then export it as .dxf and then into ie3d directly thus avoiding the painstaking process of designing the fractal geometry again for further iterations.

Also a MoM based software such as ie3d takes a lot of time to optimize the radiation,BW,gain and other characteristics and requires one to change the geometry each time and rerun the simulation for results...Pls name a software in the market for fractal antenna design that could save our time and effort in optimizing the fractal iterations for these characteristics..

Whats in my mind is this ..a software in which ..

1)One could mention the maximum return loss allowable,gain needed and then input

ONLY the basic first iteration fractal geometry

2)The software must now be able to generate results(res freq,BW,gain) for all higher iterations like a drop down menu.

3)Buttons such as optimize geometry for best bandwidth or say minimum return loss instead of a human dabbling over the geometry for a long time.

If such a thing is not possible is there a method by which a fractal design geometry done on 3rd party software(like Ultrafractal) can be imported into ie3d ?

or would CST microwave suite be better in such matters?or is there any other better solution?please help

And thanks in advance.
