A Miniaturized Printed Slot Antenna for Six-Band Operation of Mobile Handsets

A novel miniaturized multiband antenna formed by three folded slots of different lengths cut at the ground plane of the mobile handsets is presented. The proposed antenna can generate six wireless communication bands to cover GSM900/DCS1800/PCS1900/UMTS/2.4-GHz-based WLAN and Satellite DMB bands. Moreover, the antenna has a simple planar structure of small area of only 18×38 mm

. It is also promising to bend the antenna into an L shape or meander line to reduce its volume occupied inside the mobile handsets. Good radiation characteristics, gain, and radiation efficiency are obtained over these six operating bands.
