摘要
设计了一种具有双阻带的超宽带天线。该天线由一个梯形的辐射单元和一个开有矩形槽的地板构成。并且通过在地板上开L型和U型缝隙,实现双阻带特性。该结果表明,天线工作带宽(VSWR<2)为8.6 GHz(2.9～11.5 GHz),覆盖了UWB频率范围,在3.2～3.9 GHz和5～5.9 GHz处形成了两个阻带,同时,这种天线在整个工作频率范围内有良好的辐射方向特性。
In this paper,an ultra-wideband antenna with dual band-notch is proposed.It consist of a trapezoid radiation element and rectangular slotted ground plane.The band-notched characteristic is achieved by inserting slots on the ground. From the results,bandwitdth(VSWR<2)of the proposed antenna is 8.6GHz(2.9GHz～11.5GHz),which covers the whole range of UWB,and the two rejected band are formed at 3.2GHz～3.9GHz and5GHz～5.9GHz.Good radiation performance over the entire frequency range has also been achieved..
