Abstract A novel dual frequency band inverted-S antenna (ISA) using low profile PCB configuration developed for mobile handset devices in wireless communications is presented. The ISA consists of two radiating elements mounted on a small rectangular PCB with one folded element connected to the ground line and the others directly connected to the source. Two resonant frequencies are obtained at 900MHz and 1800MHz with the bandwidths over 7% and 10% at -10dB for the ISA respectively. The directional ISA (D-ISA) with dual frequency bands is also presented. The front and back ratios of D-ISA are 10dB and 7dB at 925MHz and 1790MHz respectively.
