摘　　要：分析了一种有限地共面波导结构的超短带(Ultra-wideband,UWB)槽天线单元,以及作为天线单元结构在同时同频全双工天线阵列中的应用情况。从阻抗匹配和辐射原理角度对该天线单元进行原理阐述,从全波电磁仿真层面进行分析计算,研制出原理样机进行测试验证。实测结果表明,与仿真分析一致,在8~18 GHz范围内测得的方向图与仿真分析结果具有较好的一致性。A finite-ground coplanar waveguide ultra-wideband slot antenna unit is analyzed.Its application in co-time co-frequency full-duplex array as a basic radiation element is described.The principle of this antenna unit is expatiated from the impedance matching and radiation theory perspectives.A prototype of UWB antenna is developed,tested and validated based on the analysis and computation from full-wave electromagnetic simulations.The measured results show that the experiment results are identical with the simulation analysis and the radiation pattern measured from 8GHz to 18GHz is in good agreement with simulation analysis results.
