摘要

本文提出了一种新型定向超宽带天线的设计方案。由于它的形状，它被恰当地命名为“垂直四分之一椭圆(VQE)片天线”。讨论了其模拟回波损耗、驻波比、输入阻抗和辐射方向图。该天线的电压驻波比小于2 (VSWR<;2)在2.4 GHz ~ 12.8 GHz工作带宽范围内，回波损耗(S11)小于-10 dB。这意味着操作带宽约为137%。这种巨大的增加也是由馈源位置的不对称引起的，其代价是稍微降低了辐射模式。天线的辐射方向图为“端火”型，使用反射器进行定向。并给出了增加反射镜后的模拟辐射图。

A novel directive Ultra Wideband Vertical Quarter Elliptical (VQE) Sheet Antenna design

In this paper, a novel design for a directive ultra wide band antenna has been proposed. It has been aptly named `Vertical Quarter Elliptical (VQE) Sheet Antenna' because of its shape. Its simulated return loss, VSWR, input impedance and radiation pattern are discussed. This antenna has a voltage standing wave ratio that is less than 2 (VSWR<; 2) and the return loss (S11) is less than -10 dB along the operational bandwidth of 2.4 GHz to 12.8 GHz. This means an operational bandwidth of about 137%. This tremendous increase is also brought about by an asymmetry in the feed position, the trade off being a slightly degraded radiation pattern. The radiation pattern of the antenna is of the type `end fire' which is made directional using a reflector. The simulated radiation pattern after adding a reflector has also been shown.
