研究了在单轴各向异性基板上印刷矩形微带天线的问题。考虑了各向异性对天线谐振频率和表面波激励的影响，计算了天线的雷达截面（RCS）。RCS计算包括负载阻抗（天线模式散射）的影响。将单轴衬底上贴片的谐振频率与测量结果进行了比较，并将各向同性衬底上贴片的RCS与测量结果进行了比较。给出了谱形式的单轴格林函数的推导，用关联矩法分析了微带贴片的输入阻抗和散射，以及单轴基片上源的远区场的表达式。
The problem of a rectangular microstrip antenna printed on a uniaxially anisotropic substrate is treated. The effect of anisotropy on the resonant frequency and surface wave excitation of the antenna is considered, and the radar cross section (RCS) of the antenna is calculated. The RCS calculation includes the effect of the load impedance (antenna mode scattering). Results for the resonant frequency of a patch on a uniaxial substrate are compared with measurements, and the RCS of a patch on an isotropic substrate is compared with measurements. The derivation of the uniaxial Green's function in spectral form, the associated moment method analysis for the input impedance and scattering of the microstrip patch, and the expressions for the far-zone fields of a source on a uniaxial substrate are presented.
