摘要

提出了一种CPW馈电方形分形天线。天线设计在FR4衬底εr =4.3上，厚度为1.53 mm。利用VNA对天线进行了制作和测试。实验结果显示了0.79 GHz - 2.24 GHz和3.53 GHz - 12.29 GHz的双频段。这分别对应于1.45 GHz和8.76 GHz。与传统的同轴馈电微带贴片谐振器1.44 GHz相比，天线的下端频率移位到0.79 GHz。这揭示了分形天线的尺寸减小。这种天线的实验辐射方向图在所有频率上几乎是相似的。这种类型的天线可用于GPS, pc，车载雷达和成像系统应用。

Design of dual wide band CPW-fed fractal antenna

This paper presents CPW -fed Square Shaped fractal antenna. The Antenna has been designed on FR4 substrate εr =4.3 and thickness 1.53 mm. The antenna has been fabricated and tested using VNA. The experimental result exibihits dual bands i.e. from frequency 0.79 GHz – 2.24 GHz and from frequency 3.53 GHz to 12.29 GHz. This corresponds to 1.45 GHz and 8.76 GHz respectively. The lower end frequency of antenna is shifted to 0.79 GHz in comparison to simple convention coaxially feed microstrip patch resonant 1.44 GHz. This reveals the size reduction of fractal antenna. The experimental radiation pattern of this antenna has been observed nearly similar at all frequencies. This type of antenna can be useful for GPS, PCS, Vehicular radar and imaging system applications.
