摘　　要：在印刷单极子天线上刻制零磁导率谐振器(MZR),使MZR的谐振频率低于并融合于天线的谐振频率,不但可有效减小天线整体尺寸,还可增加天线带宽。设计并制作了原型天线,测试结果表明,加载MZR后的印刷单极子天线的阻抗带宽可以显著向低频段扩展。由于天线具有电小结构,保证了辐射的全向特性和波束指向稳定性。同时基于微带线模型对MZR加载天线机理进行了讨论分析。A mu-zero resonance(MZR)resonator is etched in the patch of a printed monopole antenna.The MZR resonator generates a new resonance.As the MZR resonance is lower than the monopole and the resonances merge with each other,size reduction and bandwidth enhancement were obtained.A prototype was designed and fabricated.The test results show that the impedance bandwidth of the MRZ-Loaded monopole is extend to lower frequency remarkably.Because of the small electric structure of the antenna,the omnidirectional radiation and the beam pointing stability is well guaranteed.A microstrip line based model was built to analyze the MZR resonator antenna.
