Abstract:
This talk will present an integrated design methodology for the radiation and scattering properties of circularly polarized (CP) antenna arrays. The proposed design directly employs metasurface units as antenna radiators, achieving integration of the metasurface and the antenna, which significantly reduces design complexity. The constructed low radar cross-section (RCS) CP metasurface antenna array exhibits excellent radiation performance as well as broadband low-RCS characteristics. Conventional low-scattering antennas possess fixed scattering properties once fabricated, with their low-RCS effect confined to limited angular regions. This restricts their ability to counter emerging anti-stealth threats such as networked radar detection. To address this challenge, the talk will further present a reconfigurable scattering-beam design for CP antenna arrays. While maintaining desirable CP radiation performance, the proposed array enables flexible control of the scattered beam within a certain range, providing an effective solution against networked detection and other anti-stealth technologies.
