Abstract
En 中文
This letter presents a method for controlling the high-order mode radiation patterns of antennas through partial dielectric loading and deformation of slots, and realizes a cavity-backed low-profile wideband slot antenna for Wi-Fi 6E/7 applications. By tuning the third-order mode electric field distribution, it effectively suppresses the sidelobes, resulting in improved radiation characteristics and a wider bandwidth. The fabricated antenna prototype is a 2 multiple-input–multiple-output (MIMO) system consisting of two sets of such cavity-backed antennas. It covers an operating frequency range from 5.1 GHz to 7.8 GHz, with a single antenna height of only 3.54 mm, and exhibits a well-defined radiation pattern.
