摘　　要：微带天线具有小体积、轻重量、低剖面、可共形、易极化、易生产和低成本等优点,在航空电子和移动互联中得到了广泛应用。微带天线基片是微带天线结构的重要组成部分,不同的基片介质有不同的相对介电常数,基片介质的选择对微带天线的信号传输影响很大。基于新型双圆弧微带结构,设计一种信号传输特性优、带宽较宽的新型微带天线,并对六种不同基片介质的新型微带天线模型进行仿真,通过对仿真数据的分析比较,得出FR-4谐振抑制深度最大、信号传输损耗最小、信号输出特性最佳。The microstrip antenna has the advantages of small volume,light weight,low profile,tolerable shape pairing,easy polarization,easy production and low cost,and is widely used in avionics and mobile interconnection.The substrate of the microstrip antenna acts as an important part of its structure.Since the different substrate media have different relative permittivity,the selection of substrate medium has great influence on the signal transmission of microstrip antenna.On the basis of the new biarc microstrip structure,a new microstrip antenna with excellent signal transmission characteristic and wide bandwidth was designed,and the six new microstrip antenna models with different substrate media were simulated.The analysis and comparison results of simulation data show that the FR-4 taken as the substrate medium has the largest resonant suppression depth,minimum signal transmission loss,and best signal output characteristic.
