| 摘 要： | 本文通过谱域途径分析计算了具有波导平面混合结构天线单元的输入阻抗,用等效传输线级联模型考虑了波导及喇叭不均匀性对内场的修正.而辐射损耗则用等效波数加以处理.驻波比的计算及实测结果一致性很好.

| Abstract: | The input impedance of a planar element with mixture structure of planar substrates and waveguides is calculated by spectral domain approach in this paper. The inner fields of the structure are modified using equivalent cascade model of transmission lines when the discontinuity between the waveguide and horn is concerned. Furthermore, the radiation loss is dealt with by means of equivalent wave numbers. The computational results of VSWR agree with the measured value. |
