“…The frequency selective surfaces (FSS) are also one, two, two and half, three-dimensional periodic structures exhibiting band pass or band stop characteristics. Over the last few years, different FSS structures are proposed for miniaturization such as substrate integrated waveguide, lumped element loading, loops, patches, multi holes, and so on [93]- [96]. The twoelement patch antenna array is proposed in [97] using an electromagnetic bandgap ground plane.…”

The progress of technology in consumer electronics demand an antenna having a compact size, high gain and bandwidth, and multiple antennas at transmitter and receiver to enhance the channel capacity. Over the last decade, numerous techniques are proposed to improve the performance of the antenna. One such technique is the use of metamaterials (MTMs) in antenna design. MTMs are artificial structures to provide unique electromagnetic properties that are not available in natural materials. The unique properties of these materials allow the design of high-performance antennas, filters, and microwave devices which cannot be obtained using traditional antennas. Loading antenna with the one, two, and three-dimensional MTM structures comprised of a periodic subwavelength unit cell exhibits RLC resonant structures and allows to manipulate electromagnetic waves in the antenna system. These structures offer low resonant frequency compared to the antenna resonant frequency resulting in antenna miniaturization and manipulation of electromagnetic waves helps in enhancing the gain and bandwidth, and achieving circular polarization (CP) of an antenna system. Also, metamaterial loading enhances isolation between the antenna elements in the multiple-input-multiple output (MIMO) system by suppressing the surface waves. In this paper, the electromagnetics of MTM with analytical expressions and its application in antenna design are discussed in detail. The MTM-based antennas are classified into MTM loading, MTM inspired antenna, metasurface loading, and composite right/left hand (CRLH) based antennas. The recent development in MTM inspired antenna and its application in antenna miniaturization, enhancing gain and bandwidth, achieving CP and mutual coupling suppression in MIMO antenna systems are discussed to make it useful for further research. INDEX TERMS Circular Polarization (CP), Metamaterial (MTM), gain, bandwidth, high impedance surface (HIS), mutual coupling, antenna miniaturization, composite right/left hand (CRLH).

“…The basic FSS structure in Figure 1(a) can be equivalent to an LC parallel circuit with a resonance of f = 1/(2π √ LC). The proposed FSS structure etching a series of slots on the surface metal in Figure 1(d) is equivalent to adding extra capacitance C a and inductance L a to the basic circuit model [15], and the resonant frequency can be expressed as…”

A novel single-layer band-pass frequency selective surface (FSS) is proposed in this letter. The unit cell is composed of eight rotationally symmetrical fishbone-shaped structures surrounded by a modified octagonal loop. This fishbone-shaped FSS exhibits stable resonant frequency while the incident angle ranges from 0 • to 60 • for both TE and TM polarizations, which means that polarization insensitivity and angular stability are well demonstrated on the proposed FSS. A prototype is fabricated and measured in an anechoic chamber, and good agreements are obtained between measured and simulated results.

“…A frequency selective surface (FSS) is composed of periodically arranged patch-type units or aperture-type units and dielectric substrates, with spatial filtering characteristics. The patch-type units have a bandstop characteristic, while the aperture-type units have a bandpass characteristic [1][2][3][4]. Due to its potential values in the construction of microwave components with frequency-domain filter characteristics, FSS has been widely applied to radomes, output couplers in the infrared band, reflector antennas for frequency multiplexing, polarization converters or polarization selectors in the microwave frequency band, filters in the terahertz range, and so on.…”

This paper presents a miniaturized frequency selective surface (FSS) based on the convoluted and interdigitated stripe with multiple narrow passbands/wide stopbands in the L-/S-/C-/X-/Ku-/K-band. By using the convoluted and interdigitated stripe, the coupling inside is well controlled, so that the spatial efficiency is maximized to provide a high miniaturization. An equivalent circuit model is presented to reveal the working mechanism of the proposed FSS. The proposed structure forms four transmission band rejections of 3 dB in 1–6.65 GHz, 8.35–16.9 GHz, 18.0–24 GHz, and 24.50–27.84 GHz. The size of the unit cell is 0.09λ0 × 0.09λ0, where λ0 is the wavelength of the first resonance frequency. The proposed FSS has a good angle stability and polarization stability in a scanning range up to 60°. For verification, an FSS prototype has been fabricated and measured. The measured results were in agreement with the simulated results. The proposed FSS can be used in practical applications such as radomes, antenna reflectors, and spatial filters.
