This paper presents a novel miniaturized almost all-angle-insensitive strong coupled frequency selective surface (SC-FSS) with all-polarization-insensitive multi-band by introducing the different interlayer coupling patches. Two templates of a singlepassband and a dual-passband with unit cell less than 0.03λ are adopted to bring in two stopbands on both ends of each passband.Furthermore, the corresponding equivalent circuit models are developed to explain the physical mechanism and formulate relevant design equations. Finally, a prototype of the proposed dual-passband structure is fabricated and measured to verify the results of full wave simulation and the theoretical analysis. The experiment results show that there are a lower passband working at 2 GHz and a higher passband at 5.8 GHz with a lower stopband at 4 GHz and a higher at 7.5 GHz at the ends of above passbands respectively,which exhibits the stable performance against the variation of the incident angles (from 0° to 86°) for both TE and TM polarizations.The measurement results demonstrate that the proposed multi-band SC-FSS is a good candidate for designing a high-performance antenna radome for solving EMI problems.
