摘要：

A novel angular independent dual-band FSS with closely spaced response is discussed in this letter. The proposed single layer FSS comprises of unit cell resembling crooked cross geometry convoluted and branched to provide dual resonant paths. The FSS functioning as a band stop filter at 2.54 and 3.54 GHz works as a shielding component for S band operation. The unit cell size of the proposed FSS is where corresponds to the wavelength of the first resonant frequency. Both the bands are closely spaced providing the frequency ratio of upper to the lower resonant frequency value of 1.39. Additionally, the proposed dual-band FSS is symmetrical in nature, thereby providing identical stop-band response for both TE and TM operation modes. It also exhibits highly stable angular stability. Prototype of the proposed FSS is fabricated and its simulated results are compared with the experimental results.
