Abstract :
In this paper, a new compact PIFA applicable to PCS system is described. The Principle aim in design is to broaden the bandwidth within limited body thickness of mobile phones. To overcome the narrow bandwidth characteristic that is typical of a patch antenna a type of tapered patch is employed. The antenna is designed using CST Microwave Studio and its characteristics are compared with a basic PIFA with similar volume. In specific case, bandwidth of about 15.2% was achieved experimentally.
