Abstract
This paper presents the design of a small antenna for use in a wireless local area network (WLAN) and Wi-fi 6E on a narrow-border laptop. The dimensions of the antenna are 43 × 3 × 0.4 mm3, and it features a grounding system simulated by a 200 × 260 mm2 copper plate. At low-frequency bands, a couple-fed right arm can excite the fundamental at 2.45 GHz in the λ/4 resonant mode to cover the range of 2.4–2.848 GHz. At higher bands, the couple-fed left arm and direct-fed right arm can control the higher 3λ/4 mode at 5.825 GHz and 5λ/4 mode at 6.85 GHz. The direct-fed left arm excites the fundamental at 5.16 GHz in the λ/4 resonant mode and, with integration of 5.16, 5.825, and 6.85 GHz, can fully cover the range of 5.15–7.125 GHz. In far-field measurements, the peak gain and efficiency in a WLAN with Wi-Fi 6E were 0.82 and 2.58 dBi and 53% and 68% in the low and high bands, respectively. Overall, the experiments revealed that the antenna exhibits a sufficient level of performance for a narrow-border laptop.
Highlights
High-speed data rates are the most effective solution with wireless local area network (WLAN) called authorize user wireless mobility
With the current technology of wireless systems, high-speed downloads are limited in applications such as the Internet of things and 4K and 8K video. e end users of such products consider the upload and download speeds of WLANs to be unsatisfactory
Studies [1,2,3,4] have discovered that the guidelines for designing WLAN antennas with coplanar waveguide, slot, and bend-type architectures cannot be implemented because of limited dimensions
Summary
High-speed data rates are the most effective solution with wireless local area network (WLAN) called authorize user wireless mobility. With the current technology of wireless systems, high-speed downloads are limited in applications such as the Internet of things and 4K and 8K video. Studies [1,2,3,4] have discovered that the guidelines for designing WLAN antennas with coplanar waveguide, slot, and bend-type architectures cannot be implemented because of limited dimensions. Other studies have investigated designs such as PIFA or monopole antennas for Wi-fi applications [6,7,8,9]. Is study designed an antenna to perform in low-frequency (2.4–2.484 GHz) to high-frequency (5.925–7.125 GHz) bands by using a direct-fed arm and a couple-fed arm to enable full functionality in WLAN and Wi-fi 6E applications.
