Abstract: The Planar inverted-F antenna (PIFA) is compact antenna and it is widely used in hand-held communication terminals. Despite their favorable features of excellent performance characteristics, low-profile and flexibility of integration, the PIFA is inherently of small bandwidth. Since present day need for multi band communication by a single device, there is necessity for a multi band PIFA. The present work proposes a novel configuration of PIFA for dual band operation with bandwidth enhancement for hand-held wireless communication devices, which is achieved by modification of the physical structure of both radiating patch and of the ground plane. Simulated and measured results demonstrate that the new configuration covers two frequency bands with a considerable bandwidth improvement.
