在本文中，我们提出了一种用于超宽带应用的新型小型化共面波导馈电天线。由于其尺寸小，它可以用于身体上的应用。与传统的共面波导馈电天线不同，该天线采用两个发散的锥形缝隙。所需的阻抗带宽为3.1-10.6 GHz，VSWR < 2 dB。该天线在频带内没有表现出任何强谐振，因此表现出更少的群延迟变化，这对于保持脉冲形状非常重要。辐射方向图看起来准全向，最大增益限制在4 dBi左右。（共4页）
In this paper we propose a novel miniaturized CPW-fed antenna for ultra-wideband applications. It can be useful for on-body applications because of its small size. Unlike conventional CPW-fed antenna, this antenna employs two diverging tapered slots. The required impedance bandwidth of 3.1-10.6 GHz is achieved with VSWR < 2 dB. The antenna does not show any strong resonance within the band and hence exhibit less group delay variation which is very important to preserve the pulse shape. Radiation pattern looks quasi-omnidirectional with the maximum gain limited to around 4 dBi. (4 pages)
