摘要

提出了一种新型的多短段超宽带平面单极天线。天线的辐射贴片由一对背靠背的e形短段元件组成。类e型短杆元件是在e型短杆元件的延伸上，在e型短杆元件的背面增加两个半圆元件，在e型短杆元件的顶部增加一个带“悬锤”元件的倒l型元件。在延伸的矩形地面上蚀刻两个半圆槽，使地面具有两个阶梯状结构，实现超宽带。所述天线印刷在介电常数为4.6的基板上。实验结果表明，当S11小于- 10dB时，天线的带宽为3.2GHz-18.7GHz。

A novel multiple-stub ultra-wide band antenna

This paper proposes a novel multi-stub ultra-wide band planar monopole antenna. The radiation patch of the antenna is composed of a pair of back-to-back E-shape-like stub elements. The E-shape-like stub element is the extension of the E-shape stub element, adding two semi-circle elements at the back of the E-shape stub element and extending the top of the E-shape stub element with an inverted L-shape element with a “suspending hammer” element. Two semi-circle slots etched on the rectangular ground which is extended make the ground with two step-like structures to realize ultra-wideband. The antenna is printed on a substrate of the dielectric constant 4.6. The experiment results show that the bandwidth of the antenna is 3.2GHz–18.7GHz for S11 of less than −10dB.
