An optically transparent and angularly stable frequency selective surface (FSS) with a broad stopband is introduced for addressing millimeter wave (mmW) electromagnetic interference. The unique FSS unit cell pattern incorporates a cross patch with Y‐shaped branches, effectively broadening the bandwidth and enhancing the angular stability. Utilizing transparent conductive indium tin oxide deposited on both sides of a glass substrate enables the FSS to reflect and absorb electromagnetic waves. Consequently, the proposed FSS exhibits an exceptionally wide stopband ranging from 18.7 to 40.2 GHz, featuring an insertion loss of 14 dB and maintaining stable angular response up to 60° for both transverse electric and transverse magnetic polarizations. Moreover, an equivalent circuit model is developed to characterize the stopband behavior of the FSS. Finally, measurements conducted on a physical prototype of the proposed FSS validate its effectiveness, showing good agreement with the simulation results.

In this paper, a frequency selective surface (FSS) structure with a band-stop performance for ultra-wideband (UWB) applications is introduced. The unit cell of the FSS structure consists of a combination of a square loop, a ring loop, and a cross dipole with four gaps. The unit cell has 0.115λ g × 0.115λ g size where λ g is the wavelength in the substrate corresponding to the minimum frequency (2.79 GHz) of the operating band. The bandwidth of the FSS design is from 2.79 to 10.81 GHz frequencies (at normal incidence and |S 21 | < −3 dB criterion) which covers all UWB bands. The introduced FSS structure has angular stability up to 80°incident angles both TM and TE polarizations due to the small size of the unit cell. The highest resonance frequency deviation is 0.08% at 80°and this value is quite low. The proposed FSS structure was fabricated and the results obtained through simulations were supported by the measurement results.
