“…Single and two layer FSSs with narrow passband have been studied in [15] and [16], respectively. Parker et al studied two arrays of single-ring slots with different radii supported on either side of a thin dielectric substrate form FSS with narrow band-pass transmission responses [17].…”

Abstract-In this paper, a novel narrowband frequency selective surface (FSS) with a stable performance based on substrate integrated waveguide technology is presented. The unit cell of the FSS consists of a double-sided metalized substrate with a circular hole and a SIW circular cavity. In this way, incident EM waves enter the circular cavity and excite a TM 110 cavity resonance, leading to a narrow passband. The high-Q property of the TM 110 cavity resonance provides a very good wide-angle and polarization-independent stability. Both the simulation and experimental results show that such narrowband FSS owes its advantages to high selectivity, low profile stable performance with various incident angles and different polarizations, which is suitable for impulse detections, narrow-band communications, electronic countermeasures, etc.

“…In some applications, narrow bandpass FSSs are required to improve the out-of-band block performance, or to increase the utility and re-use of the available spectrum through increased channel selectivity and to reduce adjacent channel leakage. Attempts to the design of narrow band-pass FSSs have been made using aperture coupled microstrip patches [9], or double layer aperture dipole elements, where the response can be controlled by the relative displacement between the arrays [10], or double layer slot rings with different radii [11]. In [12], the Fabry-Perot approach is firstly introduced to design FSSs, and a diagnostic tool is developed.…”

Abstract-A design methodology of narrow band-pass frequency selective surfaces (FSSs) using the Fabry-Perot approach is presented. The whole FSS structure consists of two identical single layer FSSs separated by a foam layer, which forms a Fabry-Perot interferometer (FPI). The band-pass characteristic is a result of the FPI. The pass band can be controlled by the thickness of the foam, and the bandwidth can be controlled by the reflection coefficients of the single layer FSSs. The effects of both metallic and dielectric losses are discussed. It is interesting to note that the transmission peaks of FPI with high Q factor decline rapidly and finally disappear as the losses increase, and the insertion loss is mainly due to the refection. The relationship between the insertion loss and the Q factor of the FPI is examined. As examples, narrow band-pass FSSs at about 96 GHz with different bandwidths are designed.

“…Frequency selective surfaces (FSSs) have also been used for their state of being special to act as metallic-dielectric spatial filters in order to design dual-frequency waveguide filters [3,4]. Recently, filter designing by placing FSSs transversally into the waveguide to achieve more advantages including miniaturization, being lightweight and easy to be fabricated, have been presented [5,6]. Making multiple images of the FSS, the metallic walls of the waveguide cause the FSS unit cell to be infinite [4,6].…”

Abstract-A new band-pass narrow-band, miniaturized and single resonance within a wide range of frequency band frequency selective surface structure with lumped capacitors suitable for low frequency and narrowband waveguide filter applications is presented. The filter structure consists of five unit cells in one direction with notch square ring elements each consists of two lumped capacitors placed on the transverse plane of the rectangular waveguide. To reduce the simulation time in design procedure, split-field update FDTD method is used for the analysis of the unit cell of the analogous infinite frequency selective surface at different oblique incidence of plane waves to predict the FSS performance in the waveguide. As an application, a waveguide filter has been designed to be used in an easy to fabricate and inexpensive S-band band-pass filter. By using lumped capacitors, several undesirable higher order resonance frequencies near the dominant resonance frequency are eliminated and the waveguide filter dimensions are reduced considerably in one direction compared with the analogous waveguide filter without lumped capacitors.
