AI Technical Summary
Existing technologies struggle to achieve effective scattering performance control over a wide bandwidth and large angle while ensuring antenna radiation performance. Furthermore, they are difficult to design, have large thicknesses, and are costly, which hinders the miniaturization and integrated application of devices.
A low-profile, wide-angle, low-RCS antenna design based on a polarization-conversion metasurface is adopted. By constructing a patch antenna and a metasurface array without a metal layer, the amplitude and phase of the electromagnetic wave can be flexibly controlled by the polarization-conversion metasurface, thereby achieving enhanced radiation gain and high reduction value over a large angle.
This enables a low-profile antenna design over a wide bandwidth, improves gain performance, and achieves efficient RCS reduction over a large angle range, reducing design difficulty and manufacturing costs, which is beneficial for mass production.
