Abstract
A novel compact quad-band internal antenna for mobile handsets operating the GSM (880–960 MHz), GPS (1575 ± 10 MHz), DCS (1710–1880 MHz), and PCS (1850–1990 MHz) bands is proposed and implemented. The proposed antenna consists of a feeding strip, shorting strip, and folded loop radiating element with embedded tuning notches. Embedding the notches changes the current flow on the surface of the loop radiator so that the resonant frequencies can be controlled independently by their size and position. The measured impedance bandwidth (VSWR < 2) of the proposed antenna is 11.3% at GSM band and 27.4% at higher bands including GPS/DCS/PCS. The measured peak gains are 0.51, 2.06, 0.52, and 1.34 dBi, at the GSM, GPS, DCS, and PCS bands, respectively. © 2006 Wiley Periodicals, Inc.
