Abstract

The demand of wide range and high-accurate antennas for indoor fifth-generation (5G) positioning systems is highly required due to the higher frequencies and multipath components effects whereas indoor applications will suffer from the short-range coverage and the loss of signals inside the buildings. In this paper, a wide range, compact and multi-layer sub-6 GHz antenna design that can cover 3.4-3.65 GHz is proposed for fifth-generation (5G) new radio N78/N77 application. Three layers form the antenna structure whereas a full ground plane is placed at the middle layer. Furthermore, the bandwidth and resonant frequency vary by using different via radius which is placed between partial and full ground planes. The simulated results show that the proposed antenna has a return loss of less than -32 dB as well as a bandwidth of 250 MHz with a good impedance matching by 60% enlargement compared with the conventional antenna. The maximum achieved gain is 5.58 dBi at 3.5 GHz. Moreover, the proposed antenna radiates directionally with 95% and 65% as maximum radiation and total efficiency, respectively. It can radiate with wide-beam width of 79.9 and 242.4 degrees in xz and xy planes, respectively with respect to 3 dB angular.
未来5G室内系统的3.5 GHz多层基站天线
由于更高的频率和多径分量效应,室内第五代(5G)定位系统对宽范围和高精度天线的需求很高,而室内应用将受到短距离覆盖和建筑物内信号丢失的影响。本文针对第五代(5G)新无线电N78/N77应用,提出了一种覆盖3.4-3.65 GHz的宽范围、紧凑、多层sub-6 GHz天线设计。三层形成天线结构,而一个完整的接地面被放置在中间层。此外,在部分地平面和全地平面之间使用不同的通孔半径会改变带宽和谐振频率。仿真结果表明,该天线回波损耗小于-32 dB,带宽可达250 MHz,阻抗匹配性能较传统天线提高60%。3.5 GHz时的最大增益为5.58 dBi。天线的最大辐射效率为95%,总效率为65%。它在xz平面和xy平面上以3db角辐射,波束宽度分别为79.9度和242.4度。
