After reading your article, like to point out a few things, you have quite a good perspective on what PIFA is, it is actually evolved from IFA, which is a monopole antenna, so PIFA is really a patch+monopole antenna type. the pictures in your article show mostly IFA design theory, when it goes to PIFA you should be able to obtain quadband performance for mobile devices.
