Abstract

Conventional metal-plate antennas have been widely applied in the laptop computer as internal antennas for the dual-band or multiband mobile communications. For wireless wide area network (WWAN) and LTE communications, antennas are often required to cover several or all operating bands for the LTE700, GSM850, GSM900, DCS1800, PCS 1900, UMTS, LTE2300 and LTE2500 systems. Therefore, multiband antennas for wireless terminals and small size are emerging in the laptop computer industry. Many studies and works have been conducted to obtain single feed antennas supporting multiband operation, such as metal-plate antenna [1] parasitic branches [2] or coupled-fed [3].
