摘要
本文对无源和有源加载频率选择表面(FSS)开展了理论和实验研究,重点对弯折型FSS和二极管加载FSS开展了数值仿真和器件的设计研制,具体包括:
1.研究了弯折加载对FSS性能的影响,提出了弯折型缝隙环FSS结构,利用该新型结构成功设计实现了谐振频率为2.45GHz的单频FSS,仿真和实测表明该FSS的单元尺寸相比传统FSS尺寸大为缩小,且当电磁波入射角从0°增大到45°时,谐振频率几乎无偏移。相比集总元件加载FSS,这种弯折型FSS具有无需焊接、易设计、全平面和易于集成的优点。
2.采用弯折型缝隙环结构,利用双环嵌套方式成功设计实现了谐振频率为1.8GHz和2.46GHz的双频FSS,仿真和实测表明,该FSS不仅具有尺寸小、对入射角不敏感的优点,而且实现了单层双频谐振,更利于集成。
3.研究了二极管加载对方形缝隙环FSS性能的影响,采用更为有效和合理的仿真方法,设计实现了谐振频率为2.167GHz的二极管加载方形缝隙环FSS,仿真和实测表明:当二极管断开时FSS呈现单频透射性能,二极管导通时FSS呈现全反射性能。达到了谐振特性可电控的目的。
The paper consists of study of passive frequency selective surfaces (FSS)and study of active FSS, This dissertation focuses on convoluted slot loop FSS and active square loop FSS,The numerical simulation and the design and fabrication of FSS have been carried out. The main contributions of this dissertation are listed as following:
1. The performance of convoluted dipole FSS has been analyzed, convoluted slot loop FSS is proposed in the paper. Based on the theoretical research, An 2.45 GHz FSS with such structures is designed and fabricated, Simulation and experimental results indicate that the dimension of the loaded FSS can be miniaturized greatlyin comparison with the traditional FSS. As the angle of incidence increases from 0°to 45°, resonance frequency is with no shift. Convoluted slot loop FSS is planar and need not wielding in comparison with the traditional FSS.
2. Based on the structure of convoluted slot loop, a dual-band FSS of 1.8GHz and 2.46GHz is designed and fabricated. Simulation and experimental results indicate that the dimension of the FSS can be miniaturized in comparison with the traditional FSS. Besides, the performances of dual-band FSS are not sensitive to the angle of incidence and achieve dual-band resonance on one layer of dielectric superstate
3. The performance of square loop FSS loaded with diodes has been analyzed, and a 2.167 GHz FSS with such structures is designed and fabricated. Simulation and experimental results indicate that the resonance frequency of the loaded FSS can be electronically controlled. This active FSS design enables transmission to be switched on or off at 2.167 GHz, providing high transmission when the diodes are in OFF state, and high isolation when the diodes are ON
