Abstract

In this paper, the design and analysis of a highly efficient antenna with a low SAR rate is presented for a wide frequency band suitable for 5G mobile communications. The proposed antenna operates in N77, N78, N79 bands from 3 to 5 GHz. The antenna is designed in the form of a folded dipole antenna. It is divided into different coupled sections. Three configurations of the proposed antenna are studied based on the lower side below the folded dipole. These configurations include a complete ground plane, partial ground plane, and partial ground plane loaded with a printed EBG structure. Through this design, the return loss of −10 dB at all frequencies in the range of the antenna is achieved, and realized antenna gain equals 2.11 dB. The SAR analysis over 1 g tissue is also studied on the Hand Head Model by using CST Microwave Studio. The maximum SAR value obtained for the present design at resonant frequency 3.2 GHz is found to be 0.19 W/Kg which is quite safe for the human being.

面向5G应用的高效低sar耦合折叠天线新设计

本文针对适用于5G移动通信的宽频带，设计并分析了一种低SAR率的高效天线。该天线工作在3到5 GHz的N77、N78、N79频段。天线被设计成折叠偶极子天线的形式。它被分成不同的耦合部分。研究了三种基于折叠偶极子下侧的天线构型。这些配置包括一个完整的接平面，部分接平面，和部分接平面加载印刷EBG结构。通过本设计，实现了天线范围内各频率的回波损耗为−10 dB，实现了天线增益为2.11 dB。利用CST微波工作室对手-头模型进行了1 g组织的SAR分析。本设计在3.2 GHz谐振频率下的最大SAR值为0.19 W/Kg，对人体是相当安全的。
