Design of Laptop Antenna for WLAN and Wi-Fi 6E Applications

Abstract

This paper proposes the design of a monopole slot antenna applied to the metal ground plane of a laptop computer/notebook. The planar size of the proposed slot antenna is 27×10 mm2 and it is built on a FR4 substrate with a thickness of 0.8 mm. The proposed slot antenna is composed of a couple-feed line and two dissimilar monopole slots, in which the two slots can generate the WLAN 2.4 GHz (2400-2484 MHz) and WLAN 5 GHz (5150-5875 MHz) operational bands. Furthermore, the proposed slot antenna can also cover the recent Wi-Fi 6E operational band that covers the frequency range from 5925 to 7125 MHz.
