摘要

在这种通信中，提出了一种具有非常小离地间隙的金属框架槽天线，用于笔记本电脑。天线结构为非对称修正倒t型槽（AMITS）结构，包括长阶槽臂、短槽臂和环形狭缝。AMITS天线与金属外壳集成，连接倒l形条，覆盖2.4/5/6 GHz频段，共激发四种谐振模式。对天线进行了分析，制作了样机并进行了测量。所提出的AMITS天线具有非常小的离地间隙，仅为1.2 mm，覆盖160 MHz （2.33-2.49 GHz）和2.4 GHz （4.92-7.32 GHz）的−10 dB阻抗带宽，峰值效率为70%。低调，结构简单的AMITS天线显示了窄边框笔记本电脑在Wi-Fi 6E应用中的前景。

Metal-Frame Slot Antenna With a Small Ground Clearance for the Wi-Fi 6E Operation in Laptop Applications

In this communication, a metal-frame slot antenna with a very small ground clearance for laptop is proposed. Regarding the antenna structure, it is an asymmetrical modified inverted T-shaped slot (AMITS) structure, which includes a long step slot arm, a short slot arm, and a loop slit. The AMITS antenna is integrated with the metal casing connected with an inverted L-shaped strip, covering the 2.4/5/6 GHz frequency bands with four resonant modes excited. The antenna is analyzed and a prototype is fabricated and measured. The proposed AMITS antenna features a very-small ground clearance measuring merely 1.2 mm, covering a −10 dB impedance bandwidth of 160 MHz (2.33–2.49 GHz) and 2.4 GHz (4.92–7.32 GHz) with a peak efficiency of 70%. The low-profile, simple-structure AMITS antenna shows prospect for the narrow-bezel laptop in Wi-Fi 6E applications.
