need help simulate a microstrip array on a cone shape CST.

Hy

I have to simulate a microstrip array on a cone shape .
I have already did it on a cylinder but i have problem constructing the array on a cone .

even if i enlarge the mesh density the eror remain.

there is another problem fixing the discrete port if i have several layers.

thanks in advance

In time domain the port have to be parallel to the mesh or xyz axis switch to freq. domain
or try to rotate the antenna in the angel of the cone to get it in direction of xyz axis then build the area of the port in cube with xyz axis.
for two element try to build parallel axis patch extention and then connect the port.

I have tried to switch to freq domain but I have got the same error.

(see attached).

The idea to rotate the all structure is not viable because I can?t achieve the accuracy needed for the port location to be parallel. ( how many digits after. ).

the same file attached 13.doc

go to macro -> file -> archive you will get ziped project and then p.m. to me I'll try to solve your problem

pl

can someone please explain why the simulation work on a cylinder shape

and doesnt working with a cone shape .
