Abstract

To overcome the shortcoming of narrow bandwidth for traditional planar inverted‐F antenna (PIFA), a novel bandwidth enhancement technique for internal multiband mobile handset antennas is proposed in this article. 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 and GSM900) and high‐ (DCS1800 and PCS1900) bands. 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. © 2009 Wiley Periodicals, Inc.
