Abstract

A novel low radar cross-section (RCS) and high gain patch antenna array is proposed. A pair of slots introduced on the mushroom electromagnetic bandgap (EBG) patch realize polarization-dependency and act as parasitic radiation to enhance the antenna gain. A chessboard-like configuration composed of slot-EBG blocks is further equipped on the antenna array for scattering cancellation. Optimizing the layout pattern enables the designing of a high-gain and low-RCS antenna array using the slot-EBGs. Full-wave simulations validate that a front gain enhancement of more than 2.5 dB in the operating frequency band and low-RCS in a broad frequency band for normal incidence are obtained by the proposed antenna array.
