“…FSS functions as a spatial filter for electromagnetic waves and provides selectivity in frequency, angle of incidence and polarization of the incident waves [1]. The frequency selective characteristics of FSS allow it to be used in a wide range of commercial and military applications [2][3][4][5], EM shields (band stop/band pass filters) [6][7][8][9][10][11][12], radome design [13][14][15], RCS reduction [16,17], electromagnetic band gap materials [18,19] and absorbers [20][21][22]. Nevertheless, the FSS is widely employed in many applications.…”

This paper presents a miniaturized 2.5-D frequency selective surface (FSS) that exhibits a band stop response at frequency of 1.5 GHz. In the unit cell, the meander patterns on both sides of the substrate are connected in series by four vias. Moreover, the meandered pattern in each quadrant is also connected with one of the meander patterns of the adjacent unit cell. In this manner, a 2.5-D closed loop is created with large perimeter. The enlarged perimeter amplifies the effective inductance and leads to a decrease in both the resonant frequency and the dimensions of unit cell. Subsequently, the proposed FSS demonstrates excellent miniaturization with an overall size of 0.038 λ0 × 0.038 λ0. Moreover, the frequency response is highly stable up to 86° for both TE and TM polarization. The resonance mechanism of the designed FSS is explicated through distribution of surface current and electric field. The testing board of the proposed FSS has been fabricated for the verification of the design. The measured frequency response of the prototype are congruent with the simulation results. The distinguished features of the constructed structure are enhanced angular stability, miniaturized unit cell, low profile, simple geometry and easy fabrication.

“…Different polarization independent UWB FSS designs were analyzed [17][18][19][20][21][22]. Single layer dual sided FSS with UWB coverage are reported with polarization independence and higher incident angle stability [23][24][25]. The electromagnetic behavior of FSS structures can be analyzed using tedious mathematical modelling techniques.…”

This paper presents a compact ultra-wideband frequency selective surface (FSS) with band stop response. The proposed single layer FSS is printed on FR-4 substrate with a unit cell periodicity of 0.138λ 0 × 0.138λ 0, corresponding to its lowest operating frequency. The developed FSS exhibits stable response for plane waves with normal and oblique incidence with TE and TM polarization for angles varying from 0° to 60°. The FSS offers -10dB bandwidth of 141 % covering the entire ultra-wideband frequency range from 2.39 GHz to 13.67 GHz. The structural parameters are optimized, and an equivalent circuit is modelled to analyze the performance of FSS. The simulated results are validated by the measured values.
