This paper discusses a circular loop frequency selective surface (FSS) using a 3-D (three dimensional) printing technique. The proposed FSS design consists of a metallic patch having a circular loop printed on one side of Acrylonitrile Butadiene Styrene (ABS) material. This design is used for harmonic radar applications at 5 GHz resonant frequency. Various FSS parameters are discussed to show the effect on the resonant frequency. To make fabrication process easier and cost-effective, transmitting and receiving antennas are also printed using a 3-D printing material. 3-D printing offers cost-effective fabrication technique compared with other conventional techniques and helps in rapid prototyping. The fabricated prototype is validated with the experimental results that show good agreement between simulated results and the measured ones.

“…FSS structures are being actively studied for use in applications related to RF interference, noise reduction [19], beamforming, which reconfigures antenna radiation patterns for improved communication [20], and stealth technology in the defense sector by using features such as filtering to selectively reflect and transmit certain frequencies [21]. To employ the proposed AFSS structure, it is critical to ensure its durability and operational stability under various environmental factors, such as dust, temperature, humidity, and mechanical impact.…”

We present an active frequency selective surface (AFSS) consisting of a curved composite structure that provides structural stability and robustness. The proposed structure can operate on either the C-band (OFF state) or X-band (ON state) by controlling the PIN diode located between the cross-shaped loop and the inductive stub on the surface. Moreover, it minimizes parasitic couplings through grid-type on/off bias circuits and via holes. Thus, the AFSS guarantees isolation from the unit cell, which is a downside of a previous control technique called reconfigurable frequency selective surface. We analyzed the impact of composite structures and the three-dimensional shape on the AFSS transmission with a foam-core sandwich structure, which is light and mechanically strong, by considering conditions of a real application environment.

“…Since the past few decades, frequency selective surface (FSS) has been a subject of interest owing to its widespread applications, such as spatial filters, 1 antenna reflectors, 2 hybrid radomes, 3 absorbers, 4 high impedance surfaces, 5 and electromagnetic shields. 6 They are generally periodic structures designed to transmit, reflect and/or absorb electromagnetic (EM) waves over a desired frequency range. These FSSs are constructed by printing different metallic geometries in a periodic arrangement on either single or both sides of a dielectric substrate.…”

In this paper, a low‐profile miniaturized‐element frequency selective surface (FSS) is presented numerically as well as experimentally. The proposed design consists of a meandered pattern printed on both sides of an ultra‐thin (0.0005λ0) FR‐4 substrate, which exhibits a bandpass characteristic at 750 MHz having unit cell dimensions of 0.017λ0 × 0.017λ0. The structure, being asymmetric in nature, selectively realizes bandpass operation for a specific polarization, whereas transmits incident wave for other polarizations. The novelties of the design lie in its miniaturization performance as well as ultra‐thin profile as compared with the earlier reported structures. The proposed structure has further been analyzed through deriving equivalent circuit models and parametric variations. Finally, a prototype of the FSS is fabricated and the measured response is in good agreement with the simulated result under normal incidence.
