Abstract

This paper describes the design of a coaxial fed compact patch antenna with a centre frequency of 3.6 GHz for broadband Unmanned Air Vehicle (UAV) applications over 5G networks. A single element is designed using CST Microwave Studio software. Compared to traditional narrowband microstrip antennas, the antenna has a wider band covering the 3.4 – 3.8 GHz range thanks to a parasitic patch on top. In order to achieve a lightweight structure, the antenna proposed in this paper is designed using first Rogers RO4350 laminate substrate and then RT Duroid 5880. The particularity of this lightweight antenna relies on the use of Rohacell 31HF between the radiating patch and the parasitic one. In order to increase the gain, a 2x2 rectangular array is investigated as well within this paper. The results are compared and discussed in terms of return loss, bandwidth, gain and radiation pattern. These results show an antenna with a low profile and a simple structure that is able both to suit future 5G applications and to be a perfect candidate for future applications on board of UAVs

5G宽带无人机应用的轻型微带贴片阵列

本文描述了一种中心频率为3.6 GHz的同轴馈电紧凑型贴片天线的设计，用于5G网络上的宽带无人机(UAV)应用。使用CST Microwave Studio软件设计单个元件。与传统的窄带微带天线相比，由于顶部的寄生贴片，该天线具有覆盖3.4 - 3.8 GHz范围的更宽频带。为了实现轻量化结构，本文提出的天线首先采用Rogers RO4350层压板，然后采用RT Duroid 5880进行设计。这种轻量化天线的特殊性依赖于在辐射贴片和寄生贴片之间使用Rohacell 31HF。为了提高增益，本文还对2x2矩形阵列进行了研究。从回波损耗、带宽、增益和辐射方向图等方面对结果进行了比较和讨论。这些结果表明，一种低姿态、结构简单的天线既能适应未来的5G应用，也能成为未来无人机应用的完美候选者
