6. Rectangular attachment is put forward in order to solve the case when the feed point is near to the border of the conducting surface. it is deserved to mention that this new model is more simply than the one developed by Dr. Chen Qiang and both of them can obtain high accuracy.
6、为解决有限大长方形平面线面相连问题，文中提出了与圆形连接段互补的长方形 连接段，长方形连接段专门为解决馈电点距离边界非常近的情形而引入的。 值得 注意的是，长方形连接段的引入与陈强等人引入的连接段外加匹配段的模型相 比，前者更加简单，易于操作，同样有良好的精度。
