A multi band chip antenna is provided to improve an electrical characteristic of the antenna by controlling the impedance matching between patterns through an impedance matching unit. A multi band chip antenna of a mobile communication terminal includes a multilayer dielectric, first to third radiators(100-300), and a feeder(50). The multilayer dielectric includes at least two dielectrics(30,40). The dielectric has a hexahedral shape. The first to third radiators with the predetermined length and width are formed in the multilayer dielectric. The feeder supplies the power to the first and third radiator. The first to third radiators include at least two patterns(100a,100b,200a,200b,300a,300b) and an impedance matching unit(400,420,430). The impedance matching unit is arranged between the patterns. The impedance matching unit is one of a chip inductor or chip capacitor.
