Abstract

Abstract: In this article, the realization method and operation mechanism of suppressing cross‐band scattering is introduced, firstly. And then, a SSRs‐loaded electromagnetic transparent antenna (ETA) is designed to suppress the scattering interference existing in the proposed dual‐band shared‐aperture antenna (P‐DBSA). The P‐DBSA is composed of the proposed ETA operating in the lower‐band (LB: 1.7–2.2 GHz) and a 2 × 2 array antenna operating in the higher‐band (HB: 3.4–3.6 GHz). The proposed ETA is obtained by etching folded split‐slot resonators (F‐SSRs) on the entire radiating arms of the LB antenna. In this way, the scattered field formed by the HB‐induced current distributed on the LB radiating arms can be self‐canceled, thereby HB radiation pattern restoration can be achieved. In addition, etching F‐SSRs will not cause the ETA to be difficult to match. The proposed decoupling method has the advantages of simple in structure, high integration, and easy to manufacture, and has important reference value for suppressing cross‐band scattering existing in DBSAs.
