Design and Analysis of Planar Inverted-F Antenna for Wireless Applications
A tri-band Planar Inverted-F Antenna (PIFA) for wireless applications has been presented in this paper. The proposed antenna is compact in size and design on FR4 substrate. The antenna consists of a slotted radiator supported by shorting wall and a small ground plane. Slots in radiating patch have been used to introduce multiband operations into the proposed antenna. The structure is designed and optimized to operate at 2.02GHz, 3.06GHz and 6.1GHz with achievable bandwidths 13.5%, 10% and 16% respectively. These three bands cover the existing wireless communication frequency bands from 1.8-6.6GHz.
