ABSTRACT A compact planar inverted-F antenna (PIFA) placed on one of the two hinges of a laptop computer is proposed for wireless local-area network (WLAN) operation. The aim of this design is to integrate the PIFA’s metal surroundings as part of the radiating structure. When the PIFA is fed, resonant modes in the hinge slot bounded by the two hinges, display ground plane, and keyboard ground plane can in turn be excited. Since the 200 × 5 mm2 slot is much larger than the 10 × 5 mm2 PIFA itself, the latter, although compact and structurally simple, can be made efficiently radiating with the help of the former. Measured efficiencies are all over 50% in the desired three WLAN bands

笔记本电脑铰链上的集成平面倒 F 天线，用于 2.4/5.2/5.8-GHz WLAN 操作

摘要 放置在膝上型计算机的两个铰链之一上的紧凑平面倒 F 天线 (PIFA) 被提议用于无线局域网 (WLAN) 操作。这种设计的目的是将 PIFA 的金属环境整合为辐射结构的一部分。当 PIFA 被馈电时，由两个铰链、显示器地平面和键盘地平面界定的铰链槽中的谐振模式可以依次被激发。由于 200 × 5 mm2 槽比 10 × 5 mm2 PIFA 本身大得多，后者虽然紧凑且结构简单，但可以借助前者进行高效散热。在所需的三个 WLAN 频段中测得的效率均超过 50%
