This paper describes and validates an advanced synthesis design process of Frequency Selective Surfaces (FSS) with elliptic band-stop response. A systematic procedure based on the Generalized Chebyshev function and the extracted-pole technique enables to control the position of the transmission zeros and the attenuation level, to obtain and equiripple rejection response. A systematic process is followed to obtain the lumped LC values of the resonators circuits extracted as poles and the impedance inverters. Then, equivalent dipoles and transmission lines are obtained to carry out the electromagnetic design at normal incidence for a linearly polarized field. The impact of the high order modes of the periodic structure on the electrical response of the FSS, which can be relevant due to the stringent selected specifications, have been also analyzed. A four order band-stop filter with 3 (GHz) bandwidth centered at 30 (GHz) and attenuation 50 (dB) has been designed considering three different implementations: two filters using vacuum as transmission line with different connection lengths and a third one using dielectric substrate to enable its manufacturing. In order to verify the design procedure by experimental results, the third filter with printed dipoles in the dielectric substrate was manufactured and measured, validating the developed process.

“…These surfaces comprise periodically arranged metallic-patch elements or aperture elements within a metallic screen and exhibit total reflection (patches) or transmission (aperture) in the neighborhood of the element resonance. FSSs are often employed in the reflector antenna system of a communication satellite [1][2][3] or deep-space exploration vehicle [4 -7] for multifrequency operations. Typically, an FSS consists of one or more grids supported by one layer or multiple layers of dielectrics.…”

“…Slot-coupled microstrip antennas [1][2] are possible candidates because they can provide antenna gain of 6 -10 dBi and are easily integrated with circuit components. Several single-feed designs for slot-coupled microstrip antennas operating at two different frequencies have been reported [3][4][5]. In these designs, antennas with frequency ratios that are different …”

The frequency‐selective property of an array of rectangular dipole microstrip patches, resonant at two frequencies in the J band and two other frequencies in the Ku band, has been investigated experimentally. Measured data indicate that the electromagnetic wave transmits well through the frequency‐selective surface (FSS) in the frequency range of 8.2 to 11.4 GHz and scatters well (around 20 dB) from the FSS in the frequency ranges of 6.3 to 7.7 GHz and 12.4 to 13.9 GHz. © 2004 Wiley Periodicals, Inc.

“…FSS exhibits total reflection or transmission characteristic respectively in the neighborhood of the unit cell resonance. It has been used in many applications, such as radome, sub-reflectors of antenna [1][2][3] and superstrates above patch antenna to enhance the antenna directivity [4,5], etc.…”

Abstract-A new miniaturized bandpass fractal frequency selective surface (FSS) with excellent angular stability performance is proposed. The miniaturization has been achieved by scheming out a symmetric fractal pattern of continuous slots from the surface of a square-shaped patch, in which each periodic cell consists of incurved slot resonator for reducing the cell size. Reduction in FSS size of up to 74% with respect to the conventional square loop aperture FSS operating at the same frequency of 3.3 GHz is obtained. Furthermore, results show excellent angular stability for both vertical and horizontal polarization at different incidence angles because of its fractal configuration. A prototype is fabricated, and the FSS measurement and simulation results are presented and discussed.
