With the growing recent trends in communication, different types of antennas for various frequency ranges are being developed. Other than the operating frequency; antenna gain, return loss, VSWR and bandwidth are some of the parameters that are to be looked upon for the practicality of a particular antenna design. This review paper targets an antenna design that uses a frequency selective surfa...

Wave concept iterative procedure (WCIP) is used to analyze dual-band and enhanced band frequency selective surfaces (FSS). In the metallic U-shaped simple FSS, a fine-tune of the two rejected bands is insured by varying independently the length of the two parallel U-shaped FSS strips. The dual band response can also be obtained from the two-level rectangular conducting patches FSS. An enhanced ...

A transplantable frequency selective metasurface element (FSMSE) for high-order harmonic suppression (HS) is presented in this paper. The proposed harmonic free FSMSE can be integrated with arbitrary frequency selective surfaces (FSSs) operating at the same frequency band. The designed HS-FSMSE is applied to two different types of FSSs for verification of harmonic suppression, respectively. One...

Abstract—The scattering of electromagnetic waves from a Frequency Selective Surfaces (FSSs) composed of a new oneand two-turn square spiral shaped periodic structures are investigated by using modal expansion method for a linearly polarized transverse electric (TE) and transverse magnetic (TM) incident waves. The Moment Method (MM) of Galerkin type is employed by expressing the current induced ...

This paper deals with the theoretical investigation on a reduced sized Frequency Selective Surface (FSS). The FSS is designed by cutting a unique shaped slot into square patch. It has been shown, how the variation of the dimension of the slot and periodicity results in shifting of resonant frequency . Compared to conventional square patch FSS the designed FSS can provide reduction in resonant f...

In this paper, a novel method to design Quad-band stop frequency selective surface (FSS) is proposed shield medical/non-medical devices from electromagnetic radiation of wifi/Bluetooth, GPS,1G, 2G, 3G, 4G and 5G frequencies. The device can also be used in security surveillance protect them attack. FSS unit cell consists convoluted structures on FR4 substrate. study was performed by designing in...

In this paper, two planar Frequency Selective Surfaces (FSS) with dissimilar configurations along monopole antenna exhibiting dual-band response at 3 GHz and 5.5 is presented. One of the surfaces reflectors reflective transmissive GHz, whereas opposite for FSS in another flat reflector. Accordingly exhibits directive radiation both frequencies, however directions. Unit cell on order <inline-for...

Frequency Selective Surfaces (FSS) are increasingly being used in telecommunications systems due to the numerous advantages presented by this sort of structure, among them low cost, ease fabrication, and profile stand out. This work reports design, characterization a multilayer frequency-selective absorber (FSA) for broadband operation. The proposed structure shows an absorption performance (op...
