In this letter, a frequency selective surface (FSS) with wideband frequency response in U- and V-bands is proposed. This FSS consists of a conventional Jerusalem cross and a FAN shape on both sides of a single-layered RO4003 substrate. It exhibits a wide stopband of 30 GHz with attenuation more than 16 dB for the normal incidence. The unit cell is symmetrical in nature, thereby giving similar results for TE and TM operation modes. A panel of this FSS was fabricated and measured using free-space measurement to validate the simulation results. It is suitable for millimeter-wave shielding and reduction of mutual coupling in multiple-input-multiple-output (MIMO) antennas.
