This paper proposes a DTV/LTE antenna design without physical structure for laptop computers. By changing the laptop’s right revolving axis to a non-conductor material and exciting several dipoles and loop paths formed by the display, keyboard ground plane and metal revolving axis using a feed matching circuit at an appropriate position of the slot on the hinge to cover the frequency bands for DTV (470–862 MHz) and LTE (698–960 MHz, 1710–2690 MHz). The feed matching circuit is fitted to the keyboard ground plane adjacent to the hinge. It consists of a 3.6 nH chip inductor and a 0.2 pF chip capacitor to improve the high frequency matching and increase the high frequency bandwidth. The antenna can cover the frequency bands required by DTV and LTE, and the measured antenna efficiency in the operational frequency band is also better than 50%.

本文提出了一种用于笔记本电脑的无物理结构的 DTV/LTE 天线设计。通过将笔记本电脑的右转轴改为非导体材料，并在铰链上插槽的适当位置使用馈电匹配电路激发由显示器、键盘地平面和金属转轴形成的几个偶极子和环路路径，以覆盖DTV (470–862 MHz) 和 LTE (698–960 MHz, 1710–2690 MHz) 的频段。馈电匹配电路安装在与铰链相邻的键盘接地平面上。它由一个 3.6 nH 的贴片电感和一个 0.2 pF 的贴片电容组成，以改善高频匹配并增加高频带宽。该天线可以覆盖DTV和LTE所需的频段，在工作频段实测天线效率也优于50%。
