Abstract: A low profile planar inverted-F antenna (PIFA) is proposed for mobile handset applications. The proposed antenna covers DCS-1800 & PCS-1900 bands. The antenna consists of a square planar element suspended above the FR4 dielectric substrate. The ground plane is on the bottom side of the substrate. Overall size of the antenna is 22*22*5.2 mm3 and is well suited for mobile handsets due to its low profile, small size, wide bandwidth and good gain. The antenna geometry, simulations of return loss, input impedance, VSWR & gain are also discussed.
