Owing to the LTE (long term evolution) which can provide much higher data rate than the existing GSM and UMTS mobile networks, the internal antenna that can cover LTE/WWAN operating bands is preferred for the modern mobile communication device. All the 8-band LTE/WWAN operating bands include: three LTE bands in the LTE700 (698~787 MHz), LTE2300 (2300~2400 MHz) and LTE2500 (2500~2690 MHz), four GSM bands in the GSM850 (824~894 MHz), GSM900 (880~960 MHz), GSM1800 (1710~1880 MHz) and GSM1900 (1850~1990 MHz), and one UMTS band (1920~2170 MHz). Although there are some small-size 5-band WWAN laptop computer antennas published [1]-[5], they generally cannot satisfy the 8-band LTE/WWAN operation. In this paper, we present a promising internal laptop computer antenna with an acceptable size of 80 × 10 × 4 mm3 for practical applications. The proposed antenna is a coupled-fed PIFA with a loop feed; it can generate two wide resonant modes in the lower and upper bands to cover the desired 8-band LTW/WWAN operation.
