A compact GPS and WLAN PIFA for full metal-rimmed mobile handset using the ground bridges

This paper proposes a compact dual band PIFA (Planar Inverted F Antenna) covering GPS (Global Positioning System) and WLAN (Wireless Local Area Network) bands for the full metal rimmed mobile handset. The proposed antenna is positioned on the full metal rim which is connected to ground plane via several ground bridges as a ground contact. This ground bridge can be used to obtain the additional resonant frequency with the proposed antenna. The bandwidth has improved by adjusting the position of the ground bridge. The simulation is executed by CST simulator and the simulation result shows a good performance on return loss, efficiency, and radiation pattern.
