A compact antenna capable of generating two wide operating bands to cover the GSM850/900 (824–960 MHz) and GSM1800/1900/UMTS (1710–2170 MHz) systems is presented. The antenna occupies just 81.5(L)7(W)0.5(H) mm3 on the top edge of the supporting metal frame of the display panel, and is therefore easily embedded in the ultra-thin laptop computers as an internal antenna. The antenna is implemented using a ceramic substrate and consists of multi-branch strips. Based on the principle of the inverted-F antenna, our design yields two operating bands covering 816–983 MHz and 1703–2196 MHz can be achieved with good radiation performance for our design. The proposed antenna is thus suitable to be installed in the ultra-thin laptop computers for Wireless Wide Area Network applications.
