摘要：
In this letter, a wideband metantenna (MTA) based on the novel arrangement configuration of an artificial magnetic conductor (AMC) is proposed, and an ultrawideband (UWB) low-scattering beam scanning array is derived from it. The proposed multilayer AMC structure promotes the wide bandwidth of scattering cancellation. Synthesizing the different incidence angles of the linear polarized wave, the proposed MTA array can achieve the radar cross section (RCS) reduction of more than 3 dB in the range from 4 GHz to 47.5 GHz (11.9:1). The array composed of the MTA can achieve wideband (41.7%) low sidelobe copolarized radiation. Compared with the common checkerboard low-RCS MTA array, the MTA array with the optimized AMC configuration has higher aperture efficiency (77.7%) and smaller element spacing (0.8 lambda(0)), enabling beam scanning in the +/- 30 degrees range.
