Abstract

A new microstrip patch antenna design with a Defected Ground Structure (DGS) is described in this research for 5G V2V and V2I communication in the 25 GHz to 35 GHz frequency band. The proposed antenna improves performance and bandwidth enhancement by combining back propagation model ANN, fractal geometry, and DGS. ANN optimizes antenna size and an enhancement in bandwidth is noticed. Fractal geometry reduces antenna size and improves radiation and bandwidth through self-similarity at various scales. Additionally, this fractal-based method reduces unnecessary side lobes, enhancing performance. DGS prevent surface wave propagation, reduce cross-coupling, and boost gain. Periodic ground plane slots or patches control radiation patterns and facilitate element mutual interaction in the DGS. DGS microstrip patch antennas provide a high gain of 9 dB, a massive simulation bandwidth of 4900 MHz and measured bandwidth of 4600MHz, and a lack of mutual coupling. It’s a great 5G V2V and V2I solution for reliable communication.

未来频率下车载通信用超宽带分形微带贴片天线的设计与优化

本文介绍了一种新型的微带贴片天线设计，该天线具有缺陷地结构（DGS），适用于25ghz ~ 35ghz频段的5G V2V和V2I通信。该天线结合了反向传播模型ANN、分形几何和DGS，提高了性能和带宽。人工神经网络优化了天线尺寸，并注意到带宽的增强。分形几何通过在不同尺度上的自相似性减小了天线尺寸，提高了辐射和带宽。此外，这种基于分形的方法减少了不必要的侧瓣，提高了性能。DGS防止表面波传播，减少交叉耦合，提高增益。周期性地平面槽或贴片控制辐射模式，促进DGS中元件的相互作用。DGS微带贴片天线具有9 dB的高增益、4900 MHz的仿真带宽和4600MHz的实测带宽，且无互耦合。这是一个很好的5G V2V和V2I解决方案，可以实现可靠的通信。
