Abstract

A multi-band Sierpinski carpet fractal antenna with a modified ground plane is designed. Fractal shapes are applied on the both sides of the antenna to achieve multi-band characteristics. Sierpinski carpet fractal with iteration-3 is applied to the rectangular-shaped radiating patch. Here, the novelty of the proposed design is the modified ground plane. The ground is modified through the same fractal shape of the patch (i.e., Sierpinski here) up to 2nd iteration as defected ground structure (DGS) on a partial ground to get more resonant bands over the range of 4 GHz to 12 GHz. Moreover, partial ground helps to get better input impedance matching at the resonance frequencies. The overall dimension of the proposed structure is 45 mm x 60 mm x 1.60 mm. The proposed antenna operates at six resonant frequencies (6 GHz, 6.42 GHz, 7.09 GHz, 7.63 GHz, 9.15 GHz, and 10.11 GHz) over the range of 4 to 12 GHz with good impedance matching, good gain and efficiency. The design is suitable for different applications of C- and X-bands.

一种改进地平面的多波段Sierpinski地毯分形天线设计

设计了一种改进地平面的多波段Sierpinski地毯分形天线。在天线两侧采用分形结构实现多波段特性。将Sierpinski地毯分形迭代-3应用于矩形辐射斑块。在这里，提出的设计的新颖之处在于修改的地平面。在局部地面上，通过相同的斑块分形形状(即Sierpinski)对地面进行修改，直到第二次迭代为缺陷地面结构(DGS)，以获得在4 GHz至12 GHz范围内的更多谐振频带。此外，局部接地有助于在谐振频率处获得更好的输入阻抗匹配。拟议结构的整体尺寸为45毫米× 60毫米× 1.60毫米。该天线工作在4 ~ 12 GHz的6 GHz、6.42 GHz、7.09 GHz、7.63 GHz、9.15 GHz和10.11 GHz 6个谐振频率下，具有良好的阻抗匹配、增益和效率。该设计适用于C波段和x波段的不同应用。
