摘　　要：提出了一种基于双开口简化复合左右手(Splited Simplified Composite Right/Left-Handed,S-SCRLHs)谐振器的四陷波特性单极子天线。天线包括切割型圆形贴片、微带馈电线、带有梯形缺口的矩形地板和两个S-SCRLH谐振器,它具有四个谐振点,将S-SCRLHs谐振器耦合在新型单极子超宽带天线附近,实现四阻带功能。仿真和测量结果表明,该天线在超宽带范围内存在四个阻带,它们分别是3.6~3.8 GHz Wi Max band、4.5~4.9 GHz C band、5.6~6.0 GHz WLAN band、7.2~7.6 GHz X band。通过尺寸优化,最终尺寸定于25 mm×20 mm×1.6 mm,测量结果和仿真结果匹配较好。和其他天线相比,该天线具有尺寸小、多阻带、选择性好等特点。A novel compact ultra-wideband(UWB)antenna with a quad band-notched function using S-SCRLHs(splited simplified composite right/left-handed)resonator was presented.The antenna comprised a cutting circular patch,a microstrip feeder,a rectangular floor with a trapezoidal notch and two S-SCRLHs resonators.The S-SCRLHs resonators,which possessed4resonance points,were integrated into a novel monopole UWB antenna,the quad band-notched function of the antenna was realized.The simulation and measurement results show that there are four notch bands in the UWB range,which are3.6-3.8GHz WiMax band,4.5-4.9GHz C band,5.6-6.0GHz WLAN band,7.2-7.6GHz X band.The final size is set at25mm×20mm×1.6mm.Both simulation and measurement results are provided with good agreement.Compared with other antennas,the proposed antenna has the advantages of compact size,multi-stopband,and good selectivity.
