Hi,
I have design my MSc thesis initially in ansoft designer and was extremely difficult to design a 3D design into a 2D program and became crap. Ansoft Designer is a 2D program and Ansoft HFSS is a 3D one. In fact in HFSS you can design and 2D. As now for a project I'm suggesting you to take the following book which has title: " Planar antenna for wireless communications", Kin-Ku wong, ISBN 0-471-26611-6, Wiley
