Abstract: The present disclosure relates to a radar sensor apparatus for a vehicle, a method of detecting an object using the radar sensor apparatus, and an antenna apparatus for the radar sensor apparatus. The antenna apparatus includes N (N is an even number greater than or equal to 4) transmitting antennas and a divider. Since the divider is configured such that a preset value is set on a power ratio that is a ratio of power supplied to each transmitting antenna and a phase ratio that is a ratio of phase of a signal transmitted from each transmitting antenna, it is possible to detect a mid/long range target and a short range target simultaneously.
