Abstract

This letter presents a wideband antenna of the modified planar inverted-F antenna (PIFA), which covers GPS, DCS, PCS, UMTS, and WLAN band. The proposed antenna mainly comprises four resonance frequencies of rectangular patch, two strips and U-shaped slot, which fed by a 50Ω coaxial line, occupies a volume of 21 × 27 × 4mm3. The mobile phone considered in this study has a system ground plane of size 32 × 60 × 0.2mm3. Measured results show that the proposed antenna provides enough bandwidth to cover five bands for return loss less than -6dB (VSWR < 3). The simulated return loss is compared with measured return loss, which shows a good agreement between them.
