电磁带隙的超宽带阻带天线设计
摘要
设计了一种电磁带隙(EBG)结构。根据实际应用要求
在一种超宽带微带天线上加载电磁带隙单元
设计出一种阻带天线。对天线的多个参数进行讨论并优化设计
根据仿真实验制作出天线实物。实验结果说明:天线在3.11
5
.97 GHz的频带范围内
电压驻波比(VSWR)值大于2;在5.46 GHz处达到了9.23的峰值
阻带范围覆盖Wi MAX(3.4
3
.7 GHz)
C-band(3.7
4
.2 GHz)
WLAN(5.15
5
.35 GHz/5.725
5
.825 GHz)这三个频段
且天线增益在阻带内明显降低。
Abstract
An electromagnetic bandgap( EBG) structure is designed according to actual application requirements.An ultra-wideband( UWB) microstrip antenna is designed by loading EBG unit on a designed stop band antenna. A number of parameters are discussed and optimized
and the antenna prototype is manufactured on the basis of physical simulation. The results show that in the frequency band range of 3. 11
5. 97 GHz
VSWR value is greater than 2 and at 5. 46 GHz achieves peak value of 9. 23
stop-band range covers Wi MAX( 3. 4
3. 7 GHz)
C-band( 3. 7
4. 2 GHz)
WLAN( 5. 15
5. 15 GHz/5. 725
5. 825 GHz) bands
and the antenna gain is significantly reduced in stop band.
