By taking the rectangular metal patch on a printed circuit board as the radiation element and by cutting a C-shapedslot in the rectangular patch, a frequency band notch is implemented.
该天线采用印刷电路板上的矩形贴片作为辐射单元，通过在矩形贴片上开一个C形槽来实现陷波功能。

By inserting a slot at the edge of the rectangularslot on the ground plane and loading a C-shaped resonator near the microstrip line, dual band-notched characteristic at the central frequency at 3.
通过在地板上的矩形槽的边缘开槽和在馈线旁加载C形谐振器，该天线实现在中心频率3。
