In this paper, we present a new compact Planar Inverted F Antenna (PIFA) applicable to PCS system. The principle aim in design is to broaden the bandwidth. To overcome the narrow bandwidth characteristic, that is typical of a patch antenna, a type of tapered patch is employed. In specific case, bandwidth of about 15.2 % was achieved experimentally. And when the tapered type PIFA was applied to a specially designed mobile phone structure, the Specific Absorption Rate (SAR) value was less by 40% than that of the conventional structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
