Abstract

A novel antenna structure for UWB applications is presented. The novel antenna is based on previous research work on two layer planar UWB antennas. The novel antenna uses a radiating structure in the same plane as the ground plane, while the stripline feed is extended within the centre layer. The stripline feed couples with the elliptical shaped structure with two circular cuts. The proposed antenna is smaller size than previously reported two layers structures. A 50 Omega shielded strip-line feed with a shielding array of metal vias is employed. The ultra-wideband antenna has monopole characteristics which are confirmed experimentally.

用于超宽带应用的圆形切割椭圆天线
提出了一种用于超宽带应用的新型天线结构。这种新型天线是在前人对两层平面超宽带天线的研究基础上发展起来的。该天线采用与地平面在同一平面上的辐射结构,而带状线馈电在中心层内延伸。带线进给与带两个圆切口的椭圆结构相耦合。该天线比先前报道的两层结构尺寸更小。一个50欧米茄屏蔽带线馈线与屏蔽阵列的金属过孔被采用。超宽带天线具有单极子特性,实验证实了这一点。
