Abstract

This paper introduces a novel design concept for a triple-band Planar Inverted F Antenna (PIFA) intended for mobile communication applications. The triple-band antenna achieves its functionality through the incorporation of an L-shaped parasitic element positioned beneath the primary radiating patch of the PIFA. This design allows the antenna to operate across three distinct frequency bands: 1800 MHz and 2600 MHz for LTE Band, and 3500 MHz for WIMAX applications. Constructed with a rectangular planar element positioned above a Flame Retardant 4 (FR4) dielectric substrate and a shorting plate connecting the top radiating patch to the ground plane (referred to as the wall plate), the ground plane is situated along the bottom side of the substrate. The overall dimensions of the antenna are 48mm*60mm. Simulated radiation patterns indicate nearly omnidirectional characteristics at 1.8GHz and directional patterns at 2.6GHz and 3.5GHz, accompanied by a gain ranging from 1.02 to 4.32dBi across the three operating frequencies.
