HFSS does not allow to assign lumped port or wave port excitation on a curved surface, you should try CST or FEKO.......you will get many other options also....

John Wiley

You could use a faceted structure that will nicely approximate the curved surface. Also if the lumped port is on the edge of the bounding box then you need to add a box that is defined as vacuum.
