超宽带圆锥天线的设计

内容简介：提出了一种对圆锥天线的外部轮廓线进行改进以提高天线性能的方法。介绍了组成天线轮廓线的每个椭圆半径的设计过程,用HFSS软件对设计的天线进行仿真优化,并选定七椭圆锥凸起型天线。仿真结果表明：天线覆盖0.3～3 GHz的频带,在10∶1的频带范围内天线的实际增益大于0 dBi。

Abstract：A method to improve comical antenna performance based on external contour modification is presented in this paper.It also describes the design process of radius of each ellipse that composes antenna contour.The antenna designed is simulated and optimized by HFSS software and the seven-ellipse and convex-type cone antenna is finally selected.The results show that the frequency of the antenna ranges from 0.3GHz to 3 GHz and the actual gain of the antenna is greater than 0dBi within the frequency rang of 10∶1.
