Taking a look at Amazon I see quite a few different Books On Ham Radio and projects for Ham Radio. Even my ARRL Ham Radio Manual I bought for Electrical Engineering in college has a lot of projects especially with antennas. So I would definitely recommend buying the newest 2015 version of the ARRL Manual.You can also search on the internet and find plenty of good websites with ham radio projects. That's one of the best parts of the Ham Radio Hobby, that is homebrewing and building your own Ham Radio Projects.
Here is a short list of some websites for Ham Radio Projects.
