基于Pierrot结构的CPSS多功能集成化设计

Multi-Function Integrated CPSS Design Based on the Pierrot Cell

针对基于Pierrot结构的CPSS(圆极化选择表面)在多功能集成实现方面的发展限制,提出基于蝶形缝隙加载的双频CPSS、单谐振器双模式CPSS以及双极化可重构CPSS 3种多功能CPSS结构。双频CPSS可在8.6 GHz^9.1 GHz、12.1 GHz^12.4 GHz两个频段内实现LHCPSS(左旋圆极化选择表面)特性;双模CPSS在mode1(7.7 GHz^8.5 GHz)中为LHCPSS,在mode2(11.5 GHz^12.9 GHz)中为RHCPSS(右旋圆极化选择表面);双极化CPSS可在11.6GHz^12.4 GHz频段内实现同频段LHCPSS与RHCPSS的转化。3种CPSS结构均能实现良好的圆极化选择特性,完成目标多功能集成,增加CPSS的设计灵活性,扩展其应用价值。

In this paper,the bow-tie slot loaded dual-band circular polarization selection surface（CPSS）,single-resonator dual-mode CPSS and dual-polarization reconfigurable CPSS are presented to address the limitation of CPSS based on the Pierrot cell in multi-function integration. Dual-band CPSS is left-handed circular polarization selection surface（ LHCPSS） in 8. 6 GHz-9. 1 GHz and 12. 1 GHz-12. 4 GHz; dual-mode CPSS is LHCPSS in mode1（7. 7 GHz-8. 5 GHz）,and right-handed circular polarization selection surface（ RHCPSS） in mode2（11. 5 GHz-12. 9 GHz）. Dual-polarization CPSS could transform between LHCPSS and RHCPSS in the identical band in 11. 6 GHz-12. 4 GHz.All of these structures achieve good CPSS capability as well as multi-function integration,with the flexibility of CPSS design greatly increased and the CPSS＇s application value extended.
