A novel polarization dependent and angle resolved dual band FSS structure with band reject response is discussed in this letter. The proposed single layer FSS functions as a band stop filter with three resonant frequencies 10 GHz, 12.1 GHz, and 17.8 GHz respectively. It works as a shielding component for X and Ku-band operations. In addition, the proposed dualband FSS is asymmetrical in nature, thereby providing different band stop responses for both TE (Transverse Electric) and TM (Transverse Magnetic) operation modes. It also exhibits highly angular stability for different angles of incidences. The measurement results agree well with the simulation results. © 2020 National Institute of Optoelectronics.
