摘要

提出了一种新型的超宽带星形印刷单极天线设计方案。将平面三角形单极子贴片与其倒立构型相结合，实现星形结构。给出了两个三角形斑块相对于斑块质心的偏移位置的详细参数研究，即复合结构基底与地平面之间的距离变化。为了进一步改善阻抗匹配，在下顶点处对复合结构进行了斩波，并对偏置进给位置进行了参数化研究。该天线的最佳带宽为8ghz以上，范围从小于2ghz到大于10ghz，在整个带宽上的宽侧共极增益约为1至2dbi。

Ultra-wideband star shaped planar monopole antenna

A novel design of ultra-wideband star shaped printed monopole antenna is proposed. A star shaped structure is realized by combining triangular shaped planar monopole patch with its inverted configuration. A detailed parametric study of the offset placement of two triangular shaped patches with respect to the patch centroids, variation in distance between the base of composite structure and the ground plane, is presented. To further improve impedance matching composite structure is chopped at the lower vertex point and a parametric study for the offset feed positions is carried out. The proposed antenna yields an optimum bandwidth of more than 8 GHz ranging from less than 2 GHz to more than 10 GHz with a broadside co-polar gain of around 1 to 2 dBi over a complete bandwidth.
