具有带阻特性的新型超宽带天线的设计

open access: yes四川大学学报. 自然科学版, 2009
设计了一种具有带阻特性的超宽带天线,工作频带为2.4~12.4 GHz。为了避免与常用频段信号之间的干扰,采用在馈线终端开U型槽的方法实现了对WLAN(5.15~5.35GHz,5.725~5.825 GHz)频率范围的阻隔,阻隔频段为5~6 GHz(VSWR>2)。使用MoM数值计算对结构进行仿真,并与实测VSWR值比较,结果基本一致。仿真结果表明,相对原天线的VSWR曲线,除阻带5~6 GHz范围外,其余频段两者基本吻合,说明U型槽对于天线的作用具有独立性。

Design of A Compact CPW-FED UWB Antenna with WiMAX and WLAN Band-Notched Characteristic Evaluated in AHP Framework

open access: yesIranian Journal of Electrical and Electronic Engineering, 2017
In this article, we present a new design of a coplanar waveguide fed (CPW-fed) ultra-wideband (UWB) antenna with dual band-notched characteristics. Two notched frequency bands are achieved by using two inverted U-shaped stepped impedance resonators.
