Abstract

A compact and low-cost eight-port (2x4 configuration) tapered-edged antenna array (TEAA) with symmetrical slots and reduced mutual-coupling is presented in this paper using the inset-feed technique. The 8-port TEAA is designed and simulated using CST microwave studio, fabricated using the flame-resistant (FR4) substrate having a dielectric constant (εr) = 4.3 and thickness (h) = 1.66mm and characterized using Keysight technologies vector network analyzer (VNA). The designed 8-port TEAA operates at the 5.05-5.2GHz frequency band. Various performance design parameters, like return-loss, bandwidth, gain, 2D/3D radiation patterns, surface current distributions, and isolation-loss, are briefly studied, and the results are summarized. The eight-port TEAA has featured the bandwidth/ gain characteristic of 195MHz/10.25dB, 3dB beam-width of 52.8o, and excellent mutual-coupling (high isolation-loss) of less than -20dB, respectively. The 8-port TEAA is proposed and characterized to work for next-generation high-throughput WLANs like IEEE 802.11ax (WiFi-6E), Internet-of-Things (IoT), and the upcoming 5G wireless communication systems.

具有对称插槽和减少相互耦合的八端口锥形边缘天线阵列，用于下一代无线和物联网（IoT）应用

本文采用插入馈电技术，提出了一种紧凑、低成本的八端口（2x4配置）锥形边缘天线阵列（TEAA），该阵列具有对称的缝隙和减少的相互耦合。使用CST微波工作室设计和模拟了8端口TEAA，使用介电常数（εr）=4.3、厚度（h）=1.66mm的阻燃（FR4）基板制造，并使用Keysight technologies矢量网络分析仪（VNA）进行了表征。设计的8端口TEAA工作在5.05-5.2GHz频带。简要研究了各种性能设计参数，如回波损耗、带宽、增益、2D/3D辐射图、表面电流分布和隔离损耗，并总结了结果。八端口TEAA具有195MHz/10.25dB的带宽/增益特性、52.8o的3dB波束宽度和小于-20dB的良好互耦（高隔离损耗）。8端口TEAA被提出并表征为适用于下一代高通量WLAN，如IEEE 802.11ax（WiFi-6E）、物联网（IoT）和即将到来的5G无线通信系统。
