The use of wireless handheld devices and mobiles is increasing day-by-day and more functions and standards are integrated to a single platform that allows maximum connectivity. The planar inverted-F antenna is one of the most popular antennas used in handheld devices due to its many advantages. This paper is a comprehensive theoretical study of Planar Inverted F Antenna (PIFA). Research and experiments done on PIFA structures are discussed and categorized in the paper. The conventional PIFA has an inherent narrowband that is not desirable in most modern handheld devices.
