“…This performance comparison is tabulated in Table 2. In [15], a UWB antenna was designed for the frequency band of 2.7-13.9 GHz that employ a 6×6 array of FSS unit cells each of size 14×14mm 2 . This FSS layer increased the integrated antenna size which had produced a peak gain of 8.9 dBi and an overall gain improvement of 3.8 dBi.…”

“…Several researchers have proposed different kinds of printed monopole antennas [10][11][12] that had exhibited larger IB but with limited gain. Some of the techniques to improve the performance of the printed monopole antenna include modi ed ground plane, frequency selective surface (FSS), arti cial magnetic conductor (AMC) and so on [13][14][15]. Among them highly e cient and useful technique is the use of FSS radiator that attracts a large research attention.…”

In this manuscript, a novel high gain Microstrip Patch Antenna (MPA) is proposed using frequency selective surface (FSS) dedicated to operate at ultra-wideband (UWB) frequency domain between 3.1 to 10.6 GHz. The patch has been modified to a semi-circular shape and a partial ground technique is incorporated that also comprises a truncated semi-circular metallic plate to achieve desired high bandwidth. The FSS layer beneath the antenna has successfully augmented the gain of the antenna prototype by about 5–6 dBi. This FSS layer comprises of a 4×4 array of uniquely designed unit cells that satisfy the UWB specification and each cell size is 12×12 mm2. The integrated design provides an impedance bandwidth (IB) from 3.14 to 12.6 GHz. The proposed model finds application in the Worldwide Interoperability for Microwave Access (WiMAX) band, the C and X-band for satellite applications and in Wireless Local Area Network. The antenna is printed on a double-sided FR4 glass epoxy of 1.6mm thickness. A parametric investigation is conducted both for the FSS unit cell and the integrated design to optimize the antenna parameters to be suitable for the UWB frequency range. The optimized antenna size is 26×30 mm2 and the integrated antenna size is 51×51 mm2. The antenna prototype has provided well similarity between simulated and measured results.

“…Antenna gain is very important to the operational quality of the wireless communication system. To enhance the gain of antennas, artifcial electromagnetic structures such as artifcial magnetic conductor (AMC) [9,10] and frequency selective surface (FSS) [11][12][13][14][15] are proposed as refectors of antennas. FSS as a spatial flter [16] exhibits diferent scattering characteristics for electromagnetic waves with diferent frequencies.…”

In this paper, a high-gain flexible cylindrical antenna with rotatable curved frequency selective surface (FSS) is presented, which is designed for the 2.4 GHz industrial scientific medical (ISM) band. The array of 3 × 3 optimized FSS unit cells (102 × 102 mm2) is applied to improve the gain of the antenna (50.4 × 28 × 0.1 mm3). Through the rotation of the FSS, omnidirectional gain enhancement is realized. The simulation and measurement results demonstrate the feasibility of this work. The measured antenna with the FSS has omnidirectional high-gain in the operational band of 2.18–2.90 GHz, and the gain can be increased by 5.31 dBi at most. The antenna can be used in cylindrical conformal devices, and the proposed design method provides a new solution for gain enhancement of cylindrical omnidirectional antennas.

SummaryIn this research work, a compact‐sized offset‐fed broadband monopole antenna is designed using a frequency selective surface (FSS) reflector to enhance gain, radiation efficiency, and FBR and validated experimentally. The designed antenna consists of a triple v‐slit on a rectangular‐shaped radiating patch, a modified partial ground, and a frequency‐selective surface (FSS). It exhibits a ‐10 dB impedance bandwidth of 9.37 GHz (6.55–15.92 GHz) and a fractional bandwidth of 83.4%, yielding significant portions of the C‐band (4–8 GHz), the X‐band (8 GHz–12 GHz), and covering a considerable part of the Ku‐band (12–18 GHz). The proposed prototype equivalent circuit model has been developed progressively to validate the electromagnetic simulation results. The measured peak gain is 14.25 dBi (6.8 dBi without FSS) at 14.2 GHz with an average radiation efficiency of ≥ 96% for the FSS integrated antenna. Furthermore, the proposed design improves the front‐to‐back ratio (FBR) by 15 dB throughout the broadband frequency range. The proposed antenna peak gain, reflection coefficient (S11), radiation efficiency, and radiation patterns show adequate similarity between the tested and simulated results and have numerous advantages, including very compact size, simple structure, minimum S11 (dB), high gain, and broadband capability.
