Abstract

In this paper, a low-profile metantenna with broadband radiation and broadband radar scattering crosssection (RCS) reduction is constructed using characteristic mode analysis (CMA) method. By analyzing the modal currents of the operating modes under both x-polarized and y-polarized plane wave excitations, modifications to the metal ground, patches, and the loading of metallic vias are implemented to suppress the RCS. The simulation results demonstrate that the metantenna achieves a significant reduction of the RCS in the operating frequency band under the vertical incidence of x - and y-polarized plane waves. Furthermore, the proposed metantenna maintains good radiation performance, with a peak gain of 10 dBi and an operating bandwidth exceeding 40%.
