摘要:

本文提出了一种新型的超宽带微带阵列天线,天线由4个按H面排列的单元天线组成,天线单元是加载矩形贴片的平面印制圆形缝隙微带天线,该天线单元具有小尺寸的同时还拥有很大的带宽。整个天线由一分四的威尔金森功分器进行馈电。实验结果表明,该天线的阻抗带宽从3.1 GHz到12.4 GHz,达到了4倍频程,覆盖了整个UWB频带,同时,天线还是双向辐射,具有平面结构小尺寸的特点,适合应用于目前的超宽带无线通信系统。

Abstract:

A novel 1 ×4 planar UWB antenna array is proposed. The utilized single element is a compact planar circular slot antenna with rectangular patch which has demonstrated ultra-wideband operation characteristics. The feeding network is a 1 to 4 wilkinson power divider. Consequently,such a design is with low fabrication and assembly cost and compact size. The bandwidth of this ultra-wideband antenna array is from 3.1 GHz to 12.4 GHz and the radiation pattern is bidirectional. The performance of the antenna array is investigated both numerically and experimentally.

Key words: UWB, antenna array, circular slot antenna, compact structure
