This paper represents a simulated and experimental study of the planar inverted-F antenna (PIFA) involving the changes in the widths of shorting and feeding plates and feeding position under the radiating top plate to observe their effects on the characteristics of PIFA, which includes such as the resonant frequency, impedance bandwidth and radiation pattern. It is found that feeding plate width plays an important role in achieving a broadband PIFA. It is shown that the impedance bandwidth up to 40% can be achieved using this technique.
