摘要
可重构天线作为一种新型天线,与传统天线相比,具有体积小、功能多样、易于实现分集应用等特点,成为近年来研究的热点。应用了分形概念,通过对三阶Hilbert曲线进行几何变换,设计出一种新型的方向图可重构蝶形天线。给出了仿真与测试的回波损耗和辐射方向图。结果显示:天线在xoy平面上的两个主波瓣分别偏转了88°和60°,天线方向图对xoz平面发生反向偏转。
Nowadays the reconfigurable antenna as a new type has become the hot spot in antenna fields. Compared with the traditional antenna, it is small, versatile and easy to implement the application of diversity. The concept of fractal is used to design a novel pattern reconfigurable antenna which has a shape of butterfly shape, which is obtained through the geometry transformation of third-order Hilbert curve. The performance of return loss and radiation pattern of both simulation and measurement are also illustrated. The results show that two main lobes of the antenna proposed deflect 88° and 60° in the xoy plane respectively. It is found that the pattern achieves reverse deflection with respect to the xoz plane.
