Changes that modularization makes in antenna design

In the earliest days of the cell phone industry, one of the most awkward process of a cell phone project was integration. Modules that worked individually were put together and the whole usually failed in ways that were very difficult to find. Yet in the last decade, it seems electronic integration has largely vanished as a source of pain for projects. One of the reason is that Computer Aided Engineering (CAE) makes a large contribution towards engineering design process. However, CAE does not go to make much difference on the quality of engineering design in mobile phone. This paper provides studies on changes in the engineering design process of antenna for mobile phone caused by the introduction of information technology such as CAD, and CAE by Design Structure Matrix analysis.
