摘要

提出了一种新型的紧凑的CPW馈电超宽带天线。天线尺寸为23mm × 27mm。带宽范围为2.7 GHz ~ 10.6 GHz。该天线易于与射频电路集成,成本较低。通过参数化研究给出了天线的细节。通过改变入侵深度L2和导电面与地之间的距离g来改变带宽,从而获得超宽带。该天线工作范围为全向,具有良好的辐射效率。得到的基本参数回波损耗、驻波比、辐射方向图均符合标准要求。采用基于矩量法的IE3D仿真器对天线进行分析。

A miniaturized CPW-fed rocket shaped UWB antenna for wireless applications
A novel compact Ultra wideband antenna fed by CPW is presented. The antenna has a size of 23 mm × 27 mm. It provides band width ranging from 2.7 GHz to 10.6 GHz. The antenna can be easily integrated with radio frequency circuit for low cost. Details of antenna are presented with parametric study. The bandwidth is varied by varying the intrusion depth L2 and distance ‘g’ between conducting plane and ground and thus ultra wideband with is obtained. The antenna is Omni directional in operating range and it has good radiation efficiency. The fundamental parameters return loss, VSWR, radiation pattern are obtained, which meet standard specifications. Method of moments based IE3D simulator is used to analyze antenna.
