Abstract

The number of wireless devices is increasing daily, and these gadgets have become indispensable in people’s daily lives, requiring speedy and unlimited internet access. This may cause the currently used frequency bands to be insufficient or overcrowded. Adding the 6 GHz spectrum as a Wi-Fi 6E may assist in reducing traffic on other bands. However, the large bandwidth raises antenna design difficulties, and this article brings a new antenna proposal to this issue. It is a novel pixel patch antenna optimized by a metaheuristic optimization algorithm for Wi-Fi 6E applications. The shape of the radiating patch is determined using genetics, which is a basic algorithm based on population to achieve wideband operation. The antenna radiating element is divided into small pixel-shaped squares, then, some of them are removed for broadband operation. The antenna is constructed with the FR4 dielectric material, and it has a compact volume of 25 x 25 x 1.6 mm³. The measured impedance bandwidth of the antenna varies between 5.75 GHz and 8.46 GHz, with the maximum radiation efficiency and a gain of values of 67 % and 4.5 dBi. As a result, the suggested antenna may be employed for Wi-Fi 6E applications.

采用遗传算法的新型像素天线，用于Wi-Fi 6E应用

无线设备的数量每天都在增加，这些小工具已经成为人们日常生活中不可或缺的一部分，需要快速和无限制的互联网接入。这可能导致当前使用的频带不足或过度拥挤。增加6ghz频谱作为Wi-Fi 6E可能有助于减少其他频段的流量。然而，大带宽给天线设计带来了困难，本文针对这一问题提出了一种新的天线方案。它是一种采用元启发式优化算法优化的新型像素贴片天线，适用于Wi-Fi 6E应用。利用遗传算法确定辐射斑的形状，遗传算法是实现宽带操作的一种基于种群的基本算法。天线辐射单元被分割成小的像素形状的正方形，然后，其中一些被移除用于宽带操作。该天线由FR4介电材料构成，体积紧凑，为25 x 25 x 1.6 mm3。该天线的测量阻抗带宽在5.75 GHz ~ 8.46 GHz之间，最大辐射效率为67%，增益为4.5 dBi。因此，建议的天线可用于Wi-Fi 6E应用。
