本論文提出了一種適用於窄邊框筆電的全金屬機殼環境的槽孔天線，主要應用於Wi-Fi 6E頻段。這種天線設計直接利用筆電的金屬背蓋作為天線結構的輻射體，有效解決了金屬屏蔽效應對天線效能的影響，同時滿足現代筆電天線設計對外觀的要求。
論文中的天線設計是在金屬機殼上設計一個大小為40 mm x 1.6 mm x 1 mm的閉槽孔，這個槽孔結構是天線設計的核心部分，利用槽孔的共振特性來輻射Wi-Fi 6E信號。金屬板大小為 315 mm x 200 mm x 1 mm近似於筆電的背蓋尺寸，使用FR4玻璃纖維基板，其介電常數(εr*relativepermittivity)為4.4，損失正切(tanδ,loss tangent)為0.02，這些特性使其適合用於高頻天線設計。天線尺寸為50 mm x 6.9 mm x 0.4 mm，這是一個緊湊的設計，有利於在筆電的有限空間內安裝，天線的主體是一個單一閉槽孔的架構，通過天線輻射體與槽孔結構的耦合，產生多頻段的天線特性。這種設計可以在不同頻段上共振，涵蓋Wi-Fi 6E的6 GHz頻段，從而實現高效的無線通信。

This paper proposes a slot antenna suitable for the all-metal chassis environment of narrow-frame laptops, mainly used in the Wi-Fi 6E frequency band. This antenna design directly uses the metal back cover of the laptop as the radiator of the antenna structure, effectively solving the impact of the metal shielding effect on the antenna performance while meeting the appearance requirements of modern laptop antenna design.

The antenna design involves creating a closed slot of size 40 mm x 1.6 mm x 1 mm on the metal casing. This slot structure is the core of the antenna design, utilizing its resonance characteristics to radiate Wi-Fi 6E signals. The metal plate measures 315 mm x 200 mm x 1 mm , an FR4 glass fiber substrate with a dielectric constant (εr) of 4.4 and a loss tangent (tanδ) of 0.02 is used, making it suitable for high-frequency antenna design. The antenna itself measures 50 mm x 6.9 mm x 0.4 mm, making it compact enough for installation in the limited space of a laptop., ensuring effective integration of the antenna with the metal chassis. The antenna's main structure is a single closed slot, generating multi-band characteristics through coupling between the antenna radiator and the slot structure. This design can resonate across different frequency bands, covering the 6 GHz band of Wi-Fi 6E, enabling efficient wireless communication.
