| 英文摘要 | 设计了带三角形槽梯形辐射元和阶梯接地面的30 MMx30 MM印制单极超宽带天线原型。实验结果表明,原型天线驻波比小于2的阻抗带宽为2.8 gHz~12.81 gHz,频带内天线具有全向辐射特性,增益变化平坦,相位中心稳定。通过对原型天线振子体的缝隙加载,实现了具有带阻特性的陷波超宽带天线,其驻波比大于3的陷波频带为4.8 gHz~6.0 gHz,陷波频带内最高增益抑制为9 db,而其他频段性能与原型天线基本一致。; A trapezoid printed monopole Ultra Wide Band(UWB) antenna of the triangular cut and step ground plane is designed as the prototype,which size is 30 mm×30 mm.The experimental results show that its impedance band width is from 2.8 GHz to 12.81 GHz defined by Voltage Standing Wave Ratio(VSWR) less than 2.Over the operating band the prototype antenna has omni-directional radiating pattern,stable antenna gain and fixed phase center.By cutting a slot in the radiator of the prototype,the band-notched antenna is introduced.Its notch band is from 4.8 GHz to 6.0 GHz defined by VSWR≥3,and the largest gain rejection ratio is 9 dB.In the other working bands the band-notched antenna has the similar radiating performance with the prototype.; 福建省重大科技专项(2010HZ0004-1) |
