Abstract
A low radar cross-section (RCS) microstrip antenna is proposed. A polarisation-dependent frequency selective surface (PDFSS) structure is designed and used as the antenna ground. By properly etching the unit cells of the PDFSS with different orientations on the ground of the microstrip antenna, the RCS has been reduced in the angular range of -90 ° ≤ θ ≤ +90° in both the xoz-plane and the yoz-plane under the φ-polarised incident wave. The `Γ´ shape slots between the unit cells with different orientations are used to reduce their mutual coupling.
