Slotted ESIW Antenna With High Efficiency for a MIMO Radar Sensor [PDF]
Radio Science, 2018 AbstractThis paper introduces a slotted empty substrate integrated waveguide (ESIW) antenna for a multiple‐input multiple‐output (MIMO) radar sensor. The proposed system is based on the MIMO radar architecture. Orthogonal signals are sent from the transmitters, in such a manner that a MIMO image reconstruction is possible.
