In this paper, a Planar Inverted F- Antenna (PIFA) is designed and simulated. Slots are introduced on the radiating patch. So the antenna is able to achieve dual band resonance. The patch and the ground are shortened using a shorting pin configuration. To increase the bandwidth of the antenna, slots are also introduced on the ground plane of the PIFA structure. The radiating patch is kept on one side of substrate and substrate used in FR4. The ground is on the other side of substrate and the height of antenna is 6mm. Also as the area occupied by the antenna is small it is a good candidate in mobile systems. The simulations are performed using HFSS software. For the design dual resonance is achieved. Resonant frequencies are at 900MHz and 1800MHz with acceptable return loss less than -10dB. The bandwidth achieved is wider and covers the band used by mobile systems for communication.
