Abstract:	In this paper, we present two antenna structures with the Wi-Fi 6E band, namely, dual-slot and single-slot antennas. The presented antennas can be applied for the all-metal housing on notebook computers and also meet the requirements of notebook computer antenna design for industry. First, we introduce the design of the dual-slot antenna at the top of the metal case. The size of the dual-slot antenna was 53 × 6 × 0.6 mm3. To meet the specifications of commercially available 13-inch laptops, we chose a 305 × 205 × 1 mm3 metal case in the simulation environment. To make our proposed antenna design meet the requirement that the reflection coefficient of the Wi-Fi 6E frequency band is lower than -10 dB, we adjusted the grounded parasitic element and antenna structure to achieve the coupling effect of the slot. This antenna achieved a high screen-to-body ratio and narrow bezels and conformed with current notebook design trends. Next, because some laptops have IR cameras that require a smaller antenna, we introduce the single-slot antenna for use above the metal case. The size of the simulated metal case was also 305 × 205 × 1 mm3, and a monopole antenna with dimensions of 30 × 4.5 × 0.6 mm3 was used. By bending the geometry of the slot antenna, it can be modified to change the coupling effect. The antenna not only achieved a high screen-to-body ratio and narrow bezels, but was also smaller than the dual-slot antenna. The two proposed antenna architectures have the advantage of compactness, with the need to open only one or two slots on the metal case of a notebook computer for the Wi-Fi 6E band.
