PROBLEM TO BE SOLVED: To provide an antenna system which can be designed in accordance with a communication range. SOLUTION: The antenna system includes a power feeding part and a plurality of antenna elements. Each of the plurality of antenna elements includes a dielectric 101, via holes 71 to 78, and slots 81 and 82. The via holes 71 to 77 are arranged along a side face of the dielectric 101. The via hole 78 is arranged at the center of the dielectric 101 in a width direction DR2 and along the length direction DR1 of the dielectric 101. Each of the slots 81 and 82 is composed of a plurality of slots. A distance between a slot arranged at a position being the closest to the via hole 74 among the plurality of slots and the via hole 74, and an interval between two adjacent slots in the plurality of slots determine a communication range of the antenna system.
