Enhanced-bandwidth PIFA Antenna with a Slot on Ground Plane
In order to overcome the shortcoming of narrow bandwidth for conventional planar inverted-F antenna (PIFA), a novel bandwidth enhancement approach for internal multi-band handset antennas is proposed in this paper. In particular, a rectangular slot with an appropriate location and a proper size is introduced into the ground plane of the system printed circuit board to improve the bandwidths of handset antennas in both the low (GSM850/GSM900) and high (DCS1800/PCS1900) bands. The influences of the slot with different locations and sizes on antenna bandwidth are investigated. A prototype that can cover the frequency bands of GSM850, GSM900, DCS1800 and PCS1900 simultaneously was fabricated and measured. Good agreement between the measurement and simulation results is achieved.
