摘要
在硅衬底上设计了频率分别为11.7GHz和12.7GH的双波段缝隙天线,此设计利用RF-MEMS开关来实现天线的频率重构;天线结构紧凑、共平面波导馈电,采用IC工艺制作,为下一代无线通讯和天线集成具有重要的参考价值.采用3D电磁模拟软件HFSSR模拟了天线在低频和高频的反射损失分别为29.5dB和25dB;并且天线在低频和高频都有较高的辐射效率.
The dual-band 11.7 GHz and 12. 7 GHz slot antenna on silicon was designed. This antenna is compact, efficient, CPW-fed and using IC technology. The antenna utilizes RF MEMS switches so that this can effectively change electrical length. It is important for the next generation wireless communications and integrated antenna system on the chip. The antenna return loss is 29.5 dB and 25 dB using 3D electromagnetic simulation HFSS , at the lower and upper frequencies, respectively. Furthermore, the antenna radiation efficiency is good at the lower and the higher band.
