| 摘 要： | 本文设计了一种新型超宽带陷波天线.在超宽带微带单极子天线馈线两侧加载高阻抗表面单元,获得WiMAX频段陷波.在高阻抗表面单元上蚀刻阿基米德螺旋结构缝隙,使得单元尺寸比传统结构减小了55.2%.为了进一步在WLAN和WiMAX频段实现双陷波,将非对称的新型高阻抗表面单元加载至微带单极子天线馈线双侧.加工制作天线实物并进行测试,实测结果与仿真结果吻合良好,证明了该新型陷波单元的可行性.

| Abstract: | A novel ultra-wideband notch antenna is proposed.To obtain the notch in the WiMAX frequency band,high-impedance surface(HIS)elements are loaded on both sides of the feed line of the ultra-wideband microstrip monopole antenna.The unit size reduces 55.2%compared with the traditional structure,which etches Archimedean spiral structure gap on the high-impedance surface.To further realize double notch in WLAN and WiMAX frequency bands,asymmetric novel HIS elements are loaded on both sides of the feed line of the microstrip monopole antenna.The measured and simulated results are in good agreement,which proves the feasibility of the new notch unit cell. |
