| 摘 要： | 利用商业软件HFSS的S参数仿真结果，采用等效网络法对矩形波导宽边纵缝进行互耦环境下的导纳计算；并利用天线远场幅度、相位方向图仿真结果，采用口径场反演方法，对阵中辐射缝参数进行修正。通过设计实例，验证了该方法非常适合于平板裂缝天线阵的设计，有效地提高了设计效率。

| Abstract: | The active admittance of a rectangular waveguide longitudinal slot is determined using the S parameter simulation results of commercial software HFSS and the equivalent network method in that the internal and external mutual couplings are taken into account. The aperture distribution is determined using re-deducing method and antenna simulative amplitude/phase patterns obtained by software HFSS, and the radiating slot dimensions are modified, thus good radiation patterns are obtained. Using the proposed method, planar waveguide slotted arrays can be designed easily and economically. |
