“…By combining a coding metasurface component to design a small scattering antenna, Fabry-Perot could efficiently decrease scattering and maintain high gain, but backscattered energy band is limited [5]. With the preservation of radiation properties, two different AMC components have been intended for low scattering wideband energy [6].…”

In this summary, we have suggested a new technique in which destructive interference principle is incorporated into a chessboard like a reflective screen, and the proposed antenna realizes a remarkable in-band and also out-of-band backscattered energy reduction by using a metasurface (MS). Two different MS unit cells are designed to provide the resonant frequency with a zero-degree reflection phase. Metasurface unit cells are configured in a chessboard-like reflector screen to achieve the reflection phase difference of 180° ± 37° over a broadband range of frequencies to redirect the scattering field into four quadrants. It is implemented to reduce the backscattered energy level of the microstrip antenna, which is based on destructive interference principle. The simulations indicate that the proposed antenna possesses significant backscattered energy reduction from 6 GHz to 16 GHz in both x– and y– polarization and also −10 dB backscattering reduction at antenna working band (7.4–7.8 GHz) is covered. Moreover, the radiation performance is preserved well and artificial magnetic conductor (AMC) unit cells work at different frequencies which are not influenced on the radiation properties. The bistatic performance of the antenna at different frequencies is also presented. Measurements and simulations of the fabricated design coincide well and the proposed design is verified and validated successfully.

An efficient approach is presented in this article, to reduce radar cross section (RCS) of a microstrip patch antenna, without affecting other radiation characteristics by the application of a novel hybrid metamaterial (MM) structure. The microstrip antenna is designed to operate at 4.2 GHz. Three different configurations of MM structures (ie, CB_1, CB_2, and hybrid) with splitted square and ring shaped two nonidentical MM cells are designed and critically analyzed in the range of 2‐18 GHz. A hybrid MM configuration is chosen for the design and implementation of low RCS antenna due to its exceptional performance as compared to CB_1 and CB_2. The hybrid MM is organized in chessboard configuration, comprises of splitted square and ring shaped MM unit cell. The results show that proposed antenna gives substantially out of band RCS reduction from 6 to 18 GHz and the proposed antenna has a lower RCS than the reference antenna. Proposed antenna attains wideband bandwidth around 7.4 GHz (ranging 2.0‐4.4 GHz, 7.8‐9.1 GHz, and 14.3‐18 GHz). The maximum reduction of −30.1 dBsm at 16.4 GHz is achieved in the hybrid MM structure impinged microstrip patch antenna. Finally, the fabrication and performance evaluation of MM loaded antenna is carried out. Moreover, measured results of the fabricated samples are closely matched with simulated results, which prove the effectiveness of the adopted approach for practical applications.

“…Out of band and In band RCSR achieved is around 17 and 13 dB respectively. Hao Jiang et.al [17] proposed an antenna with partially reflecting surface (PRS) and high gain for out of the band and in band RCSR. In-band RCS is achieved by using a metamaterial ground plane.…”

In this paper, we have discussed and summarized the techniques of radar cross section reduction (RCSR). RCSR has been prompted due to the evolution of military technology. The paper reviews the basic concepts and characteristics of metamaterials, as these are the most favorable development that impacts defense industry products and stealth technology. This paper emphasizes the role of airpower and the ever-increasing demand for stealth. Initially, the blending of the fundamental aspects of stealth technology through radar signatures and methods of signature reduction are discussed. Then, the description of metamaterials and detailed analysis of their properties is made. This paper review the fundamental properties of metamaterials. It also explores the recent research activities on metamaterials in various areas. Some existing researches techniques used for RCSR are examined. The metamaterials are engineered media whose electromagnetic responses are different from those of their constituent components. The general benefits of metamaterials are pointed out in the paper. Metamaterials are mostly used in antenna configuration for enhancing antenna performance such as realizing miniaturization, expanding the operating band, enhancing gain as well as reducing RCS. These characteristics of the metamaterials are basically the reason why metamaterials should be used in stealth technology. The various categories of metamaterials used for RCSR are studied in the paper. In this paper, we have also proposed a unit cell. The unit cell consists of a square loop and intersecting strips at the edges of add shaped structure.
