This paper deals with a modified planar inverted F‐antenna designed to operate at 2.3 GHz. The modifications are done with an intention of achieving wide bandwidth. It involves the simulation of a basic PIFA, for which dual U‐Slots are deployed and in order to obtain wider bandwidth the concept of the partial ground is taken into consideration. The main motivation behind this is to achieve an impedance bandwidth over 1 GHz which will prove to be useful in addressing several types of wireless and mobile applications. The simulated findings show that proposed PIFA achieved a bandwidth of 1.35 GHz (55.9%) with a gain close to 4.98 dB. The new antenna's size 20 mm × 10 mm (L1 × L2 mm) was compact and the fabrication cost is also less. The fabricated prototype was tested and measured and a good agreement was observed between the simulated and the measured results.
