改进的圆形超宽带印刷单极子天线

内容简介：给出一种新型紧凑的带陷超宽带印刷单极子天线,天线由圆形辐射贴片和有限接地平面组成.天线输入端驻波比小于2的带宽覆盖3.38-20 GHz频率范围,具有16.62GHz的绝对带宽和142.7%的相对带宽.在整个频带范围内,方向图H面近似全向且对称.仿真与测量结果验证了该天线的优越性,该天线可以方便用于超宽带无线通信领域.

Abstract：A simple and compact microstrip-fed ultra wideband (UWB) printed monopole antenna is presented.The antenna is composed of a circular radiator and a finitely grounded plane.The antenna occupies about 16.62 GHz absolute bandwidth and 142.7%relative bandwidth covering from 3.38 GHz to 20 GHe with voltage standing wave ratio (VSWR) below two.A quasi-omnidirectional and quasi-symmetrical radiation pattern in H plane is obtained in the whole bandwidth.The high performance of the antenna is validated with measured and simulated results given.The antenna can be applied for the system design of UWB wireless communication.
