Title of Paper:Multiple Frequency Cancellation Method for Stealth Design of UWB End-Fire Antenna Array

Journal:Trans. Nanjing Univ. Aero. Astro.

Abstract:A multiple frequency cancellation (MFC) method is proposed for stealth design of ultra-wide band (UWB) end-fire antenna array. The proposed method can produce significant radar cross section (RCS) reduction in the whole operating band. The 1×4 and 4×4 Vivaldi antenna arrays of different kinds of cancellation structures are discussed as examples to validate the effectiveness of the MFC method on both linear and planar arrays. On average, 22.6 dB reduction of monostatic radar cross section (MRCS) is obtained in the whole X-band. MRCS under oblique incident waves is also reduced within ±60°. Basically favorable radiation characteristics are maintained. © 2018, Editorial Department of Transactions of NUAA. All right reserved.
