“…7 shows to be at least 20 dB higher than previous works [6,9], and also having a very narrow band of rejection. Moreover, this characteristic will contribute in the RCS reduction out of the antenna's band, as there will be very low reflections for frequencies higher than 4.2 GHz.…”

“…As the demand for the stealth budged in warfare increases, researches have been published in the open literature which shows that radar backscatter suppression can be achieved using thin carbon based microwave absorbers and resistive metamaterials [6][7][8][9]. Frequency selective surfaces are mainly used as microwave filters, for applications such as frequency separation in satellites [10].…”

“…In this kind of work, the FSS is used as a resonator, and acts like a partial reflective surface [14]. In [15] a great RCS reduction was reported within the antenna's band, but results for the reflection coefficient show that out of band the RCS increases with frequency . Additionally, Turpin [16] reported a good RCS reduction within 1-12 GHz, for an antenna based on absorbing materials.…”

This paper presents a method for reducing Radar CrossSection (RCS) of an increased gain metal backed dipole antenna. Numerical simulations were done and compared to a laboratory experiment. The results show that when a Perfect Electrical Conductor (PEC) is replaced by a Frequency Selective Surface (FSS), the antenna is still able to perform with the desired characteristics, but the RCS of the structure is greatly reduced out of band. The design of the FSS and the return loss, gain improvement, and RCS are presented for an antenna operating at 4.2GHz, and the results are compared with a conventional metal backed layout. Measurements show a good agreement with the simulations, and so the advantages on other structures from the reviewed literature are mentioned.

“…It is widely used in fields such as satellite communication [2], antenna beam-steering [3], electromagnetic shielding [4], meta-materials integration [5] and radar cross section (RCS) reduction [6][7][8] based on its spatial filter characteristics of electromagnetic (EM) waves such as bandpass or bandstop response. However, performance requirements for FSSs are different according to application environments.…”

Abstract-An annular-ring element for building a miniaturized bandstop frequency selective surface (FSS) structure which possesses a superior performance with respect to electromagnetic wave polarizations and incident angles is introduced in this paper. The proposed element has prominent miniaturization characteristics with a unit dimension of 0.061λ × 0.061λ, where λ represents the freespace wavelength corresponding to resonant frequency. Miniaturization of the proposed FSS element is achieved by constructing special meandered strips in geometry and arranging lumped components between the elements. The advantage of this method lies in its great simplicity in tuning the resonant frequency of FSS by adjusting values of the printed capacitors rather than rebuilding the geometry. The obtained FSS also exhibits a stable performance in terms of angle stability and polarization insensitivity. Prototypes of the proposed FSS are fabricated and measured to verify design method. Measurements are well in line with simulation results.

“…Frequency selective surface (FSS), as a typical artificial composite structure, has been extensively applied in antenna RCSR [9][10][11][12][13][14][15][16]. In [17], a Fabry-Perot cavity antenna based on partially reflecting surface (PRS) technology is proposed.…”
