The present invention is related to a horizontally polarized wave antenna using a serial-feed mode. The antenna includes: a feeder line configured to receive a current supplied from a feeder unit installed to a vehicle; and a patch antenna unit configured to radiate an electromagnetic wave in a horizontal direction while being installed to serially extend in a vertical direction with respect to the ground in a shape that is bent in a zigzag form. The patch antenna unit includes a plurality of first patch elements and a plurality of second patches. With this arrangement, it is possible to realize a horizontally polarized wave with a high resolution by composing vectors of currents flowing in respective patch elements while keeping the entire size of a radar system small.

A wheel fixing unit includes: a body; a plurality of wheel connectors protruding forward from the body and connected to a tool connection hole in a wheel of a vehicle; and a cable connector protruding rearward from the body and including a connection terminal formed on a protruding end side such that a cable is connectable thereto. A calibration device using the wheel fixing unit includes: wheel fixing units respectively coupled to left and right wheels of a vehicle; a target board installed spaced apart in a direction corresponding to a vehicle body and configured such that a transmission signal of a sensor mounted on a front or rear surface of the vehicle body is reflected by a reflector and is incident on the sensor; and an interval maintaining cable connected to one end of the wheel fixing unit and one of the both sides of the target board.
