twisting aluminium problem

[J.C.Maxwell]

hi all.
i have a small piece of 6061 aluminum with 6cm length. i want to twist it by 45 degree.
how can i do it.
this device is an antenna and will be used in 6-18GHz.
i want to know if i can heat this device and rotate it by 45 deg with linear step?
or some other ways to manufacture it.

You could consider design it splitted into thin laminated pieces so that could be glued one by one.
It would be necessary to design a jig to guide the parts during the assembly.

thank you andre.
is it applicable to manufacture it as one part (by wire cutting or Spark) and then heat it and twist by som device?
if yes , is it reasonable to heat and twist such frequency sensitive device ?

thank you

I don´t know what technique is used to manufacture metallic parts having such an intricate geometry to be honest, but the approach that seems more feasible is not to cut a solid piece, but rather to split the original draw into many sheets ( such as sections of a tomography ) and assemble all them stacked, turning a little each plate at the appropriate angle.

In order to provide an anti-aliasing of the inner surface, could finish in nickel or another material suited for this application.
