ABSTRACT

A wideband antenna with excellent efficiency is the most important requirement in wireless communication. In this paper, a wideband and highly efficient planner metamaterial-based microstrip patch antenna is proposed and examined. The proposed patch antenna is designed whose size is 12 × 16 mm² and has a metamaterial unit cell loading on the top patch and the bottom ground plane. The top unit cell, which consists of four triangular shapes capacitive coupled resonator (TSCCR) and the bottom unit cell, which is square-shaped with diagonal cross-slot (SSDCS) is loaded on patch and ground respectively. The proposed antenna gives impedance matching of −10 dB for frequency band 2.88–14 GHz. The antenna's highest gain of 7.2 dBi at 12.39 GHz, positive gain range of 1.5–7.8 dBi in its operating band, and average efficiency of 75% are attained. The wideband and high gain properties of the proposed antenna make it suitable for UWB (3.1–10.6 GHz), Wi-Max (3.5 and 5.8 GHz), 5G NR FR1 (3.3–5 GHz) and Wi-Fi 6E (5.59–7.12 GHz) application.

摘要

具有出色效率的宽带天线是无线通信中最重要的要求。在本文中，提出并检验了一种基于宽带高效规划器超材料的微带贴片天线。所提出的贴片天线的设计尺寸为 12 × 16 mm ²并且在顶部贴片和底部接地平面上加载了超材料晶胞。由四个三角形电容耦合谐振器 (TSCCR) 组成的顶部单元和带有对角交叉槽 (SSDCS) 的方形底部单元分别加载在贴片和地面上。拟议的天线为 2.88–14 GHz 频段提供 −10 dB 的阻抗匹配。该天线在 12.39 GHz 时的最高增益为 7.2 dBi，在其工作频段内的正增益范围为 1.5–7.8 dBi，平均效率为 75%。拟议天线的宽带和高增益特性使其适用于 UWB (3.1–10.6 GHz)、Wi-Max (3.5 和 5.8 GHz)、5G NR FR1 (3.3–5 GHz) 和 Wi-Fi 6E (5.59–7.12 GHz）的应用程序。
