“…In general, a FSS can be designed based on the transmission line theory to predict the desired transmission characteristics. Figure 23 shows a newly developed low profile muti-layer FSS (Behdad et al, 2009), which applied the third-order bandpass frequency response, with an overall thickness of only λ/24. Each layer is a two-dimensional periodic structure with sub-wavelength unit cell dimensions and periodicity, where both resonant and non-resonant elements have been combined and miniaturized.…”

“…In recent years, a new class of FSS with low-profile feature is intensively studied, as it is reported by the authors in [10][11][12][13][14][15]. This class of FSS structure is studied and realized at X-band frequency range.…”

Abstract-In this paper, we propose the design of multilayer frequency selective surfaces (FSS) waveguide band-pass filters (WBPF). The WBPFs are designed to operate at two different frequency channels, respectively 71-76 GHz (Rx) and 81-86 GHz (Tx). The cross section surface of the FSS is imposed by the WR12 waveguide rectangular section's dimensions. The WBPFs are inserted symmetrically in a T-junction waveguide to design a compact diplexer. This is a basic component developed for an efficient integration in the future E-band millimeter-wave transceiver. The multilayer FSS structure uses only non-resonant sub-wavelength unit cell elements; metallic patch and slot. To reach high channel isolation (≈ 70 dB) a seven order filter was required. Hence, each filter is composed of 13 capacitive and inductive metallic FSS spaced by 12 ultra-thin dielectric substrate layers. The dielectric material is Rogers Ultralam 3850 (Liquid Crystalline Polymer; LCP circuit material). The filter's overall thickness is < λ/4. The numerical studies have been performed using finite element method simulator (HFSS) and CST Studio Suites Tools. The experimental validation has been also done in the X band frequency by developing a fifth order FSS WBPF. Good agreements between simulated and measured results are obtained.

“…Complementary FSSs by using Babinet principle had been investigated in [18,19]. Coupledresonator spatial filter (CRSF) FSS was firstly introduced in [20] and further investigated in [21][22][23][24], in which two microstrip patches are coupled through an aperture to form a higher-order bandpass filter. Substrate integrated waveguide (SIW) technology was proposed by Luo et al [25][26][27] to design high performance FSSs, in which the SIW cavity is formed by arranging metallic via array around each periodic slot.…”

Abstract-In this paper, a waveguide filter using miniaturizedelement frequency selective surface (FSS) is presented. The proposed FSS is composed of periodic array of metallic patches separated by small gaps and metallic lines. The array of patches constitutes a capacitive surface and the lines a coupled inductive surface, which together act as a resonant structure. At about 5.0 GHz, a narrow bandpass response is designed. Dimensions of the FSS element are much smaller than the operating wavelength, which is less than 1/13λ. For this miniaturized element, grating lobes are restrained and do not appear event to 25 GHz. Moreover, the FSS has stable performances for various incident angles. Design procedure and measurement results of the FSS are presented and discussed.
