关于宽缝隙微带贴片天线的端口激励问题

建模完成后有这样的错误： 
    Port refinement, process abc3d : There are no tetrahedral faces assigned to boundary "Imped1".  Since boundary operations are order dependent, please check to make certain that this boundary is not being ignored because of other operations on the same surface.  It is recommended that you redefine the boundary in question. 见附件。我对微带线的边界问题不太明白，还有端口激励问题，请问哪位高人能帮我解决一下，或者提供些资料，先谢谢啦
