Conformal and Highly Compact Wi-Fi 6E Antenna for Laptop Applications

Abstract

A conformal and yet highly compact Wi-Fi 6E antenna is proposed for laptop applications. A planar topology is first utilized that is later conformed for achieving highly compact antenna structure. The conformal antenna geometry occupies a minimal area of $\boldsymbol{9.5\times 4.7}$ mm2. A thin FR4 substrate of thickness 0.2 mm is used to achieve conformity. The antenna consists of a meandered monopole strip capacitively coupled for exciting the $\boldsymbol{\lambda/4}$ resonant mode in the 2.4 GHz band. A rectangular loop is also connected to the monopole strip for the excitation of the $\boldsymbol{\lambda/2}$ loop resonant mode in the 5 GHz band. The L-shaped coupling trace produces the $\boldsymbol{\lambda/4}$ monopole resonant mode in 6 GHz band. The antenna may be the first conformal design for laptops.
