提出了一种用于便携式无线设备的无线广域网（WWAN）和长期演进（LTE）八频段天线，其由具有片式电感的直馈式天线、接地条和具有分布式电感的耦合馈电式天线组成。这三个分量的基模形成从0.66到1.03 GHz的低工作频带。接地带和耦合馈电微带的高模产生了1.7至2.87 GHz的高工作频带。基于6dB的回波损耗，这两个宽工作频带可用于LTE 700/GSM 850/900/1800/1900/UMTS/LTE 2300/2500应用。所提出的尺寸为75 mm、10 mm、0.8mm的天线适用于平板电脑的顶部边缘。一块200 × 260 mm的铜板（约为13英寸屏蔽板的大小）用作系统接地层。
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$\,\times\,$10$\,\times\,$0.8 mm$^3$ is appropriate for the top edge of a tablet computer. A 200 $\,\times\,$260 mm $^2$ copper plate, which is about the size of a 13-in screen plate, is used as the system ground plane.
