基于RLC等效电路结构的双陷波超宽带单极子天线
资料介绍
在超宽带通信内,为了消除频率范围为3.8-4.8 GHz和5.1-5.6 GHz窄带信号,设计了一种双陷波单极子天线。天线包括一个椭圆形的辐射贴片和一个矩形的接地面,由50Ω微带线馈电。为了获得频段抑制特性,在馈线附近放置了两个蘑菇形的电磁带隙结构,提出了该结构的等效RLC电路。天线的输入阻抗和电压驻波比进行了仿真验证。天线的工作频率为2.9-11 GHz,且除了两个陷波带外其通带内VSWR<2。
For the purpose of eliminating narrow signals in ultra-wideband communication,which frequencies are 3.8-4.8 GHz and 5.1-5.6 GHz,a dual band-notched monopole antenna is proposed.Antenna is fed by 50Ωmicrostrip feedline,consists of a elliptical radiating patch and a rectangle ground plane.Two mushroom type electromagnetic band gap structures are positioned near the feedline in order to achieve band rejecting characteristics,and equivalent RLC structure is designed.The impedance and VSWR(voltage standing wave ratio)are validated by simulation.Antenna operates at frequency from 2.9 GHz to 11 GHz,which VSWR<2 except for two band notched.
