“…Whereas, the FSS reported in the literature 2-6,9-16 uses expensive dielectric material. • The designed FSS is rotational symmetry and thus seems to be polarization insensitivity and angularly stable, while the FSS demonstrated in References [1][2][3][4], [8][9][10], and [10,11] are asymmetric, hence their resonance characteristics changes with the incidence angle of wave and on the orientation of FSS. • The reported FSS can be easily redesigned for changing over its resonant frequency between 1 and 5 GHz by simply varying the length of the convoluted structure in each of three layers.…”

A novel ultra-miniaturized frequency selective surface (FSS) based on a triple layer of the convoluted metallic strip is presented in this article. The interconnection of metallic convoluted strips in each layer to one another by PTH holes increases the electrical length of FSS and thus reduces the resonant frequency to 1.23 GHz and hence the unit cell is miniaturized. The proposed FSS realizes a wide stop band centered at 1.23 GHz with a -10 dB impedance bandwidth of 400 MHz. The size of the unit cell is 0.024 λ o Â 0.024 λ o , which is atleast 29% smaller than the similar literature works. To demonstrate the validity of design, the FSS of size 30 cm Â 30 cm accommodating 2500 unit cells with a periodicity of 6 mm is fabricated, tested, and verified with the measurement result. The FSS provides a stable response up to the incident angle of 60 for both transverse electric and transverse magnetic operating modes. Furthermore, the proposed FSS is polarization insensitive because of its rotational symmetry. The proposed FSS finds suitable for the applications of GPS, aircraft surveillance, astronomy and mobile services, and so on.

“…There have a great number of studies on miniaturized FSSs, such as closed loop and complementary structures [15,16,17,18,19], loading with passive lumped elements (capacitors and inductors) [20,21,22,23], coupling technology based on capacitive and inductive surfaces [24,25,26], and 2.5-D knitted structures [27,28,29]. A miniaturized FSS with double pass-band was designed in [15], which was based on the closed loop and its complementary pattern.…”

A miniaturized dual-band frequency selective surface (FSS) is proposed in this letter. The FSS unit cell is composed of meander lines arranged spirally, and produces resonant frequencies of 1.42 GHz and 3.76 GHz with -3 dB bandwidths of 0.95 GHz and 0.49 GHz. The equivalent circuit model is introduced to explain the FSS performance. The meander lines at top and bottom layers are connected through copper vias to increase the equivalent inductance and capacitance of the FSS unit cell. The dimension of the unit cell is 10 mm, which is about 4.7% of the wavelength at the first resonant frequency. Simulation results show that the proposed FSS can work stably at resonant frequencies for both TE and TM polarizations while the incidence angle varies from 0 to 60 degree. A prototype of the FSS is fabricated and measured. The measurement results show reasonable agreement with the simulated results.

“…Miniaturized FSS can be used to overcome the above difficulties. Many methods are employed to achieve the purpose of unit size reduction, including the coupling technology based on the capacitive surface and inductive surface [13][14][15], loading with passive lumped elements (capacitors and inductors) [16,17], and the unit curling and interdigitating design [18][19][20][21][22][23]. In [18], a convoluted structure is used for miniaturized FSS, and the element size is about 0.08 wavelength of the free-space.…”

The work presented in this paper concerns a method for the miniaturized frequency selective surface (FSS) based on the meander lines. A miniaturized dual-bandstop FSS structure based on meander lines with spiral-shape is proposed and simulated. The equivalent circuit and current distributions are introduced to explain the FSS performance. The size of the unit cell is 10 mm, which is about 0.037 wavelength at the first resonant frequency. Simulation results indicate that the proposed FSS has a frequency shift smaller than 1% for different polarizations with an oblique incident angle of 60°. A prototype of the FSS is fabricated and measured. The measurement results show that the FSS is polarization-insensitive and angle-insensitive.
