提出了一种利用寄生条和寄生缝隙改善超宽带多边形缝隙天线陷波特性的小型化天线。该天线具有一个寄生带嵌入内的多边形槽和一个隔离狭缝中采用的斜T型短截线。通过选择寄生带和缝隙的尺寸,可以获得理想的带陷超宽带工作特性。该天线具有18×24× 0. 8 ×mm的小尺寸和近全向辐射方向图,适合于各种便携式UWB天线应用。
A compact UWB polygon slot antenna with improved band-notched characteristics using a parasitic strip and a parasitic slit is presented. The antenna has a parasitic strip embedded inside the polygon slot and an isolated slit employed in the bevelled T-stub. The desired excellent band-notched UWB operation can be obtained by choosing the sizes of the parasitic strip and slit. The proposed antenna has a small size of 18×24×0.8×mm, and a nearly omnidirectional radiation pattern, which is suitable for use in various portable UWB antenna applications.
