A circularly polarized (CP) Fabry-Perot (FP) resonator antenna with well radar cross section (RCS) reduction property is presented in this article. Wideband and well in-band RCS reduction for both x-and y-polarized waves are obtained by the proposed antenna. A polarization conversion metasurface (PCM) is designed to make the antenna realize circularly polarized radiation and RCS reduction simultaneously. The PCM consists of two unit cells which show same polarization conversion capability but 180 reflection phases difference when the wave incident from the top side. The polarization conversion capability can make the antenna realize circularly polarized radiation, while the chessboard arrangement of two unit cells can reduce the RCS of the antenna. Besides, the high reflectivity of the PCM also make the antenna obtain high gain and well in-band RCS reduction property. The radiation and scattering performance of the antenna is verified by the measured results of the fabricated antenna. The antenna obtains maximum gain of 13.9 dBic at 10 GHz and average RCS reduction of 10 dB in the band of 6-16 GHz. Besides, the RCS reduction of the antenna at 10 GHz for both polarizations are all large than 14 dB.

“…However, these devices are complicated to fabricate. The metasurface is an unconventional method for controlling the phase, amplitude, and polarization of EM waves based on the generalized Snell's law (Yu et al, 2011;Lin et al, 2014;Xie et al, 2020;Hu et al, 2021a). The subwavelength structure, ultra-thin thickness, and low cost make it widely used in various fields, such as broad diffusion (Wang et al, 2014;Gao et al, 2015a), beam steering (Zhang et al, 2018), polarization conversion (Cheng et al, 2014), cloaking (Tan et al, 2022) and focusing (Cai et al, 2020;Hao et al, 2021;Lu et al, 2021).…”

Programmable metasurfaces have attracted significant attention in various applications such as radar and 6G communications, owing to their ability freely shape the far-field pattern. However, complex calculations and simulations are always required when designing specific far-field patterns, especially when irregular obstacles are outside the metasurface. In this article, we propose a method using a four-layer artificial neural network to realize the far-field radar cross section (RCS) prediction of programmable metasurfaces in an environment with obstacles, and the prediction value agreed with the simulation data reasonably well. Results show that the proposed prediction model is characterized by better learning and generalization capacity. Our work has broad application prospects and value in complex environment signal transmission, metasurface inverse design, etc.

“…Many different approaches have been presented for RCS reductions such as frequency selective surfaces (FSS) [8][9][10], metasurfaces [11][12][13][14], partially reflecting surfaces [15], electromagnetic bang gap (EBG) structures [16], and artificial magnetic conductor [17,18]. Different authors have presented parasitic stubs or slots openings in the antenna structure or in the antenna ground plane to control in band RCS [19][20][21][22][23].…”

In this paper, an ultra-wide band modified slot-sinuous antenna has been designed to enhance bistatic radar cross section (RCS) response. The design procedure consists of adding three or five parasitic ellipses openings to each of the slot-sinuous arm cells. The parasitic ellipsis allows to control bistatic RCS without impacting antenna radiation characteristics. Parasitic ellipses opening dimensions are small compared to the relative wavelength of the signal on each active region of the antenna. The ellipses distributed on sinuous antenna arm are scaled by the same expansion coefficient used to design the antenna itself. In the proposed design, ellipses parameters such as ellipses axis, radial position, and relative angle position on the sinuous cell are key parameters to be optimized for bistatic RCS reduction. The total number of designing parameters is finite, but their combination is infinite, which leads to the possibility of designing different antennas based on the required designing goals. The proposed solution and the results presented in this work show the applicability of the designing parameters to control bistatic RCS on active region antennas.
