| 摘 要： | 以研究超介质结构在天线中的应用为目的,采用了超介质理论中的负折射率传输线(NRI-TL)加载技术,设计了一种三工作频段的单极子贴片天线.该单极子天线由不均匀弯折线构成,采用共面波导(CPW)馈电.在2.45 GHz和55 GHz附近弯折线与超介质结构可形成折合单极子辐射；在3.55 GHz附近超介质结构可改变天线表面电...

| Abstract: | Aiming to apply the metamaterial structure to the antenna,a tri-band printed monopole antenna is proposed which uses Negative Refractive Index Transmission Line(NRI-TL) metameterial loading.The monopole is consisted of a nonuniform meander-line,feeding by Coplanar Waveguide(CPW).The meander-line and the metameterial loading can be modeled as a folded monopole at 2.45 GHz and 5.5 GHz,while the metameterial loading changes the direction of the surface current across the antenna around 3.55 GHz.Thus,it can inc... |
