  • Antenna device for radar system
    Patent number: 10158181
    Abstract: The present invention relates to an antenna device for a radar system, comprising: a power supply unit; and a plurality of radiators disposed to be spaced from the power supply unit, wherein each radiator is formed according to a variable determined by a weight predetermined for each radiator. According to the present invention, the performance of the radar system can be improved by obtaining uniform performance of each radiator by forming each radiator according to the weight for each radiator.
