A multi band antenna for a vehicle is provided to give a multi frequency band through a single antenna by using a high harmonic band having a fundamental frequency band of a radiation unit. A multi band antenna for a vehicle includes a printed circuit board(100), a radiation unit(110), and a feeding unit(120). The printed circuit board(100) is formed inside a radome which protects an antenna. The radiation unit(110) is formed to be optimized by a hilbert type of a meander line on the printed circuit board(110), and generates a resonant frequency of a multi band. The feeding unit(120) applies a signal to the radiation unit(110). The meander line of the radiation unit(110) is composed of a single pattern, and is symmetrically formed on both planes of the printed circuit board(100). The printed circuit board(100) is a shark shape of a streamline. |
