Abstract

Next generation multiple-input multiple-output (MIMO) radar system poses challenges of requiring wideband, high gain, and multiple uncorrelated antennas for achieving better resolution than traditional phased array radar systems. A MIMO antenna with electromagnetic band-gap (EBG) reflector is developed for uni-directional radiation pattern. The wide in-phase bandwidth in EBG is thus necessary for wideband MIMO radar application. The spiral-like slot is placed between two antennas to cancel the transverse electric field component produced by the reflected wave from the reflector. The MIMO antenna achieves high isolation and stable uni-directional radiation pattern within C band (4-8 GHz) applications.
