PROBLEM TO BE SOLVED: To provide an integrated antenna system capable of obtaining a configuration of three-dimensionally arranging a plurality of kinds of antennas at a low cost and easily attaining precision of tilt angles. SOLUTION: A GPS antenna 20, a VICS antenna 21, an ETC antenna 22 are individually mounted on three mount pieces 23a, 23b, 23c of a mount base 23 formed by bending a metallic plate respectively. Tilting the mount pieces 23b, 23c of the mount base 23 can direct the VICS antenna 21 in the arrival direction of a radio wave from a radio wave beacon installed on a road and direct the ETC antenna 22 in the direction of an antenna installed at the tollbooth of an express highway. Since the mount base 23 is formed by bending the metallic plate for providing easier and more inexpensive working processing in comparison with that of a thermoplastic resin made insulation board of prior arts, the configuration of three-dimensionally arranging a plurality of kinds of the antennas 20 to 22 can be obtained at a low cost and the precision of the tilt angles of the mount pieces 23b, 23c can easily be attained.
