蝶形平面超宽带（UWB）天线的设计

一种蝶形平面超宽带（UWB）天线的设计

内容简介：超宽带无线通信技术以其低功耗、高带宽、低复杂度等优点而倍受重视，使用蝶形结构设计了一种新的平面超宽带天线。该天线由同轴馈电，天线的制作是通过在介质基板上下面上分别印刷一个半圆形金属，在上层刻蚀掉2个正方形图案，下层刻蚀掉2个半圆形图案实现。仿真和实物实测结果都可以证实，天线的工作频带为3．1—10．6GHz，有很好的全向辐射方向图和良好的线性相位响应。因此，该天线的特性能够满足超宽带的要求，可用于无载波超宽带无线数据通信系统。

Abstract：Ultra Wide Band （UWB） wireless communication technology which has a range of good features of low-power, high bandwidth, low complexity and other advantages are being highly valued. A novel planar antenna with bowtie shape for UWB applications is presented. The proposed antenna fed by coaxial probe is created by printing a semicircle metal on both sides of the substrate with two squares etched from the top layer and two semicircles etched from the ground respectively. The simulated and measured results have shown that the designed antenna covers the 3.1-10.6 GHz band with well behaved omnidirectional radiation pattern and linear phase response. Accordingly, the proposed antenna is capable for Carrier-free ultra-wideband wireless data communication system.
