提出了一种带双陷结构的共面波导馈电的平面超宽带天线。天线采用矩形贴片作为辐射单元,采用共面波导(CPW)进行馈电,通过在矩形贴片上开一个U形槽和在接地面上开2个对称的L形槽来实现双陷波功能。
A planar ultra-wideband antenna fed by coplanar waveguide with double-trap structure is proposed. The antenna uses a rectangular patch as the radiating element, fed with coplanar waveguide (CPW), with dual notch function by opening a U-shaped slot in the rectangular patch and two symmetrical L-shaped slots in the ground plane .
