Abstract

This paper presents a novel planar stepped fat monopole antenna for ultra wideband (UWB) applications. A drawback of a planar fat monopole antenna, relatively narrow bandwidth is overcome using stepped arms, and then UWB behavior of the antenna is obtained. For an easy feeding, a coplanar waveguide technique is used. For optimum design in terms of return losses and constant gain, the antenna is simulated with a commercial EM simulation tool. For verification, a prototype antenna is fabricated. From the numerical and measured results, the antenna has better than 10 dB return loss in the bandwidth between 2.2 GHz and 7 GHz.
一种用于脉冲波形精确定位系统的新型阶梯式胖单极天线
本文提出了一种用于超宽带(UWB)应用的新型平面阶跃式胖单极天线。采用阶梯式臂克服了平面胖单极天线带宽较窄的缺点,从而获得了天线的超宽带特性。为了便于馈电,采用了共面波导技术。为了在回波损耗和恒定增益方面进行优化设计,使用商用电磁仿真工具对天线进行了仿真。为了验证,制作了一个原型天线。从数值和实测结果来看,该天线在2.2 GHz ~ 7 GHz带宽范围内回波损耗小于10 dB。
