Abstract

In this paper, a compact elliptical shaped UWB fractal antenna is proposed. The excitation is done with a double stepped coplanar waveguide feed. The frequency characteristics of proposed antenna consist of ultra wideband properties in the range 2.85 GHz to 15 GHz corresponding to the impedance bandwidth of 136.13%. The measured radiation patterns are bidirectional in E-plane and Omni-directional in H-plane. The simulated peak gain is 5dBi at 10.6 GHz. The areas of applications are modern wireless communication, penetrating radar, vehicular radar, and medical imaging.

超宽带应用椭圆形分形天线的设计
本文提出了一种紧凑的椭圆型超宽带分形天线。激励是通过双阶共面波导馈电完成的。该天线的频率特性包括2.85 GHz ~ 15 GHz的超宽带特性,对应的阻抗带宽为136.13%。测量的辐射方向图在e面是双向的,在h面是全向的。在10.6 GHz时,模拟峰值增益为5dBi。应用领域包括现代无线通信、穿透雷达、车载雷达和医学成像。
