Abstrak

ABSTRACT A polarisation conversion metasurface (PCM) is proposed to realise broadband radar cross section (RCS) reduction of a slot array antenna. The PCM's unit cell, whose polarisation conversion ratio (PCR) is more than 88% from 8.41 to 32.28 GHz under x‐and y‐polarised normal incidence, consists of two pairs of v‐patterns with gradually narrowing widths and a pair of rectangular patterns. The wideband RCS reduction of PCM is achieved by chessboard structure. Simulated and measured results prove that the application of PCM reduces wideband RCS. The proposed PCM can realise the RCS reduction outside the antenna's operating band. The 10 dB RCS reduction ranges from 8.7 to 34.8 GHz under normal incident wave with no polarisation insensitivity.
