本文提出了一种适用于5G移动的通信的宽频带的具有低SAR率的高效天线的设计和分析。所提出的天线工作在N77，N78，N79频段从3到5 GHz。天线设计成折叠偶极子天线的形式。它被分成不同的耦合部分。基于折叠偶极子下方的下侧，研究了所提出的天线的三种配置。这些配置包括完整接地平面、部分接地平面和加载有印刷EBG结构的部分接地平面。通过这种设计，在天线范围内的所有频率下，回波损耗均为− 10 dB，实现的天线增益为2.11 dB。利用CST Microwave Studio对1g组织进行了SAR分析。在谐振频率为3.2 GHz时，本设计获得的最大SAR值为0.19 W/Kg，这对人体来说是相当安全的。
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.
