Disclosed is a method for determining an impedance matching circuit of a vehicle radar of the present invention. According to the present invention, the method for determining an impedance matching circuit comprises the following steps: selecting a plurality of points separated by a preset distance among points corresponding to a preset reflection loss based on an origin of a Smith chart; designing an impedance matching circuit corresponding to a characteristic value of impedance on the origin and the preset matching point; and determining a printed circuit board (PCB) with the smallest insertion loss among PCBs individually including the designed impedance matching circuit as a PCB with a frequency band desired to use. |
