One of the key enablers of future wireless communications is constituted by massive multiple-input multiple-output (MIMO) systems, which can improve the spectral efficiency by orders of magnitude. However, in existing massive MIMO systems, conventional phased arrays are used for beamforming, which result in excessive power consumption and hardware cost. Recently, reconfigurable intelligent surface (RIS) has been considered as one of the revolutionary technologies to enable energy-efficient and smart wireless communications, which is a two-dimensional structure with a large number of passive elements. In this paper, we propose and develop a new type of high-gain yet low-cost RIS having 256 elements. The proposed RIS combines the functions of phase shift and radiation together on an electromagnetic surface, where positive intrinsicnegative (PIN) diodes are used to realize 2-bit phase shifting for beamforming. Based on this radical design, the world's first wireless communication prototype using RIS having 256 2-bit elements is designed and developed. Specifically, the prototype conceived consists of modular hardware and flexible software, including the hosts for parameter setting and data exchange, the universal software radio peripherals (USRPs) for baseband and radio frequency (RF) signal processing, as well as the RIS for signal transmission and reception. Our performance evaluation confirms the feasibility and efficiency of RISs in future wireless communications. More particularly, it is shown that a 21.7 dBi antenna gain can be obtained by the proposed RIS at 2.3 GHz, while at the millimeter wave (mmWave) frequency, i.e., 28.5 GHz, a 19.1 dBi antenna gain can be achieved. Furthermore, the over-the-air (OTA) test results show that the RIS-based wireless communication prototype developed is capable of significantly reducing the power consumption.

A reconfigurable polarization rotation surface (PRS) using chessboard‐like geometry is introduced for the radar cross section (RCS) reduction of a Yagi‐Uda antenna in this article. The reconfigurable PRS reflector can be switched between low‐RCS PRS reflector and metal reflector. When the reconfigurable PRS reflector with ON‐state diodes is used in the Yagi‐Uda antenna, the antenna has a similar radiation characteristic compared with Yagi‐Uda using metal reflector. The PRS reflector can be used to achieve a low‐RCS characteristic reflector by chessboard configuration with OFF‐state diodes. Finally, the status of RCS can be switched according to the working state of diodes. The results show that the radiation performance of the Yagi‐Uda is preserved. The monostatic RCS of the Yagi‐Uda using PRS reflector with OFF‐state diodes can be reduced more than 25 dB.

“…The implementation of the existing reconfigurable polarization converters can be divided into two methods. One method is to change the dielectric materials [16][17][18][19][20][21], the other is to change effective metal structure by using electronic devices [22][23][24][25][26][27][28][29][30][31][32][33]. The former method uses materials such as liquid crystals [16], graphene [17], [18], metal fluid [19], [20], vanadium oxide (VO 2 ) film [21] to replace the traditional metal and dielectric materials, this method has the characteristics of high frequency band and difficult fabrication.…”

In this paper, a novel reconfigurable metasurface (NRM) with coincident and ultra-wideband linear-to-linear (LTL) and linear-to-circular (LTC) polarization conversion functions is proposed. The unit of the proposed NRM consists of superstrate, air layer, metal patch, substrate and metal ground successively. By loading micro-electromechanical system (MEMS) between two adjacent metallic via, the proposed NRM can realize LTL and LTC polarization conversion efficiently. Numerical simulation results reveal that the bandwidth of LTL and LTC polarization conversion are coincident from 5.7 GHz to 23.5 GHz (fractional bandwidth of 122%). It is worth mentioning that few metasurface in existing literature can achieve highly coincident and ultra-wideband LTL and LTC polarization conversion functions. Finally, measurement results are in accordance with simulation results.
