“…Several techniques have been used to enhance the antenna gain of linearly polarized microstrip patch antennas (LP-MPAs). Use of the electromagnetic band-gap (EBG) and frequency selective surface (FSS) as a superstrate has been proposed by Pirhadi et al [5]. Also, use of metamaterials as antenna substrates has been proposed by Enoch et al [6] and Wu et al [7].…”

Abstract-This paper proposes a metamaterial reflective surface (MRS) as a superstrate for a single-feed circularly polarized microstrip patch antenna (SFCP-MPA). It illustrates a simultaneous enhancement on antenna gain, impedance bandwidth (ZBW) and axial-ratio bandwidth (ARBW) by adding the MRS atop the SFCP-MPA. The MRS can enhance the ZBW and ARBW by 3.5 and 9.9 times, respectively, compared to the circularly polarized patch source. Moreover, the gain of the CP-MPA with the MRS is 7 dB higher than that of the conventional CP-MPA. The small spacing between the MRS and patch source is another merit in the present design, which is as low as λ • /16, as it results in a low-profile antenna design that well suits modern wireless communications.

“…Another important phenomenon is the effect of the p on the resonance condition of the structure. If the periodicity is close to the wavelength, multiple resonances is achieved and may be used in the design on multi-resonance FSS structure [13] and for the wide band rejection smaller loop is required.…”

“…It is noted that the square loop FSS (SLFSS) offers the better performance in terms of angular stability, cross polarization, bandwidth and band separation [1]. Due to these unique properties, single square loop frequency selective surface (SSLFSS) and double square loop frequency selective surface (DSLFSS) have been investigated by several researchers [10][11][12][13]. Moreover, to analyze the FSS, various numerical techniques have been developed where each one is associated with its own merits and demerits [14].…”

Abstract-In this manuscript, a simple synthesis method of single square loop frequency selective surface (SSLFSS) is discussed, which may find the suitable application in the fast analysis and fabrication of the frequency-selective surface. The presented technique is used to design SSLFSS at 3 GHz, 15 GHz, 22 GHz and 26 GHz. At every frequency of interest, the analytical result is very close to the required result. Moreover, a way to control the reflection at any frequency is discussed, which may find an application in controlling the reflection level at any frequency. However, we have proposed two simple, cheaper and lightweight structures at 3 GHz and 22 GHz for the application in various satellite communications. The proposed process has been extended to the analysis of bandpass structure and desired results have been achieved, which indicates the utility of the method of synthesis of both the bandpass and bandstop structures.

“…Later, the PBG-type superstrate was substituted with a frequency selective surface (FSS) that was able to control a reflection phase of the superstrate resulting in a resonance length reduction between the superstrate and a ground plane [2,3]. Antenna resonating at multiple frequency bands was also reported in [4], which equipped with a superstrate composed of double dielectric slabs of different dielectric constants.…”

Abstract-A new approach to analyze the behavior of a FabryPérot cavity type high-gain antenna covered with a frequency selective surface (FSS) superstrate is presented. Using an image theory and effective constitutive parameter retrieval, properties of impedance and a refractive index of the entire cavity structure are investigated. Through the analysis, we show that our antenna inherently operates in the medium whose maximum magnitude of the refractive index is lower than '0.5'.In consequence, we demonstrate that the high-gain feature of the Fabry-Pérot cavity antenna is not only due to satisfy a conventional cavity resonance condition, but also for a wave collimation effect of a metamaterial with the effectively low index of refraction. To show the collimation effect of the cavity, phase properties of a radiating wave with and without the FSS superstrate are examined. Moreover, the effect of the real and imaginary parts of the refractive index on behaviors of the antenna is also investigated by analyzing the derivative of a realized gain of the antenna within an impedance matched frequency band.
