PROBLEM TO BE SOLVED: To surely connect a radiation element and a feed line to a power feeding part by soldering and to prevent electrolytic corrosion between a small-sized ground substrate and a ground substrate. SOLUTION: An antenna system 1 comprises a ground board 2, a small-sized ground substrate 3 which is formed smaller than the ground board 3, includes a ground pattern 3d and includes a first conductor pattern 3b and a second conductor pattern, and a radiation element 4. The radiation element 4 is connected to the first conductor pattern 3b and the second conductor pattern of the small-sized ground substrate 3 by soldering, and the small-sized ground substrate 3 and the ground board 2 are fixed in the state of overlapping via a dielectric layer 3e.
