Abstract :
A Wireless Wide Area Network (WWAN) and Long Term Evolution (LTE) eight-band antenna for portable wireless devices is proposed, which consists of a direct-fed monopole with a chip inductor, a grounded strip, and a coupled-fed monopole with a distributed inductor. The fundamental modes of these three components form a low operating band from 0.66 to 1.03 GHz. The higher modes of the grounded strip and coupled-fed monopole create a high operating band from 1.7 to 2.87 GHz. Based on the 6-dB return loss, the two wide operating bands can be employed in LTE 700/GSM 850/900/1800/1900/UMTS/LTE 2300/2500 applications. The proposed antenna having dimensions 75×10×0.8 mm3 is appropriate for the top edge of a tablet computer. A 200×260 mm2 copper plate, which is about the size of a 13-in screen plate, is used as the system ground plane.
