“…The band-stop FSS of 2.41 GHz, and 1.50 GHz were designed for EMI reduction applications. In [4][5][6][7][8][9][10] and [19][20][21][22][23][24][25][26][27][28][29][30], researchers have proposed unique designs to mitigate the effects of EMI and to improve isolation in UWB and 5G applications [31][32][33]. However, some important parameters of FSSs such as thickness, bandwidth, fractional bandwidth, periodicity, signal attenuation, angular stability for horizontal and vertical polarizations schemes need to be further investigated to enhance the performance of the FSS for EMI reduction applications.…”

A low-profile ultra-wideband (UWB) band-stop frequency selective surface (FSS) is designed for S-, C-, X-and Ku-bands communication applications. The FSS is constructed by using square and circular loop elements printed on the top and bottom sides of the RO3210 substrate. The FSS has been designed to reduce the electromagnetic interference (EMI) as well as to mitigate the harmful effects of electromagnetic radiation on the human body caused by different radio devices. The dimension and size of the UWB FSS have been reduced to 0.12 λ× 0.12 λ and 90%, respectively, as compared to the reported literature. The other advantages of the proposed FSS are that it is low profile, it has a simplified geometry and it ensures better angular and polarization stability of up to 85 • . The -10 and -20 dB bandwidths of the proposed FSS are 146% (2.0-13.0 GHz) and 80% (4.87-11.42 GHz), respectively. Theoretical results have been obtained using ANSYS HFSS and verified through measured results.

“…To avoid these problems in the CATR's setup, reducing the measurement distance, a compact and cost effective solution based on a metasurface lens, is introduced in this work. Metasurface lenses based on a Jerusalem-cross structure have been widely used for higher gain antennas with low sidelobes at sub-6 GHz, and most of them have not been integrated with antennas [18][19][20][21][22][23]. In [24], a very small focal-to-diameter (F/D) ratio transmitarray for generating a high-quality QZ at 2.6 GHz was proposed, but few studies have been conducted on millimeter waves.…”

With the development of communication technology has come several measurement applications requiring plane-wave conditions for wireless-device characterizations in anechoic chambers. In this paper, a metasurface lens with a 2 × 2 feeding-antenna array is proposed and characterized to synthesize a plane wave in a near field for a fifth-generation (5G) millimeter-wave radio-frequency (RF) devices test. The metasurface lens, based on Jerusalem-cross elements printed on a printed circuit board (PCB) substrate, is used for controlling the phase-shift distribution of incident spherical waves. The lens has a size of 0.4 × 0.4 m and is designed to operate at a range from 24.25 GHz to 27.5 GHz, and its feeding-antenna array is located at a focal plane of the lens, which is parallel to the metasurface lens. The lens is studied and verified through simulations and experiments, and a uniform amplitude and phase-field distribution at a reduced distance of 1.2 m generated by the metasurface lens throughout a QZ are achieved. The worst-case amplitude and phase variation of the designed metasurface lens are ±0.75 dB and ±7.5°, respectively. The results show a plane-wave condition can be achieved in 5G millimeter bands through the proposed compact and effective metasurface lens. Moreover, the proposed metasurface lens is shown to be capable of reducing the plane-wave synthesizing distance compared to the compact antenna test range (CATR) with a significantly reduced system cost, making it an attractive alternative to antenna testing in 5G millimeter-wave frequency bands.

“…Unfortunately, it achieves broadband transmission but does not absorb EM. Some recent work on Jerusalem-crossbased FSS has been published [20][21][22][23]. However, it only has narrow pass and stop bands, in addition to the 2D FSR.…”

This article designs a frequency-selective rasorber (FSR) with a broadband transmission window. It is synthesized by a broadband absorber and a frequency-selective surface (FSS). The resistive layer achieves broadband absorption by introducing a tortuous Jerusalem cross load with lumped resistors, and the lossless FSS adopts a three-layer metal structure to realize the broadband transmission window. The absorption mechanism of the resistive layer is analyzed using the theory of characteristic mode. The position of the resistor is determined according to the analysis of mode current distribution and parameter optimization. Prototypes of the structure were fabricated and measured, and the simulation results show that the 1 dB transmission window and the absorption band with |S11|< −1 dB are 36.4% and 97%, respectively. Therefore, the designed FSR has potential application prospects in electromagnetic stealth technology and radar cross-section reduction.
