WebJan 1, 2024 · Similarly, a reduced RCS patch antenna consisting of a metasurface having 3-bit coding linear PCM elements is presented by Wang et al. [23]. In [24], Liu et al. present a F-P antenna using chessboard PCM for wideband RCS reduction. Measured results show quite good impedance matching from 8.48 to 12.2 GHz, the peak gain of 17.2 dBi, and a ... WebJun 14, 2024 · In [], the design of the metasurface-based antenna array with low RCS properties was presented. Compared with the same-sized PEC, the metasurface-based antenna array reduces >10 dB RCS in a relative bandwidth of about 21%. In [–], a new concept of coding metasurfaces was introduced based on optimisation algorithms. オールドルーキー 子役 有吉
