1. An antenna module comprising:
a ground electrode having a first slit that forms a first opening along a perimeter of the ground electrode;
a first antenna and a second antenna arranged in or on the ground electrode; and
a coupling reducing electrode connected to the ground electrode within the first slit,
wherein the first slit is provided on a path leading from the first antenna to the second antenna along the perimeter of the ground electrode,
wherein the coupling reducing electrode comprises a first conductor having a first length corresponding to a first frequency and a second conductor having a second length corresponding to a second frequency, the second frequency being higher than the first frequency,
wherein the first the first slit comprises a plurality of convex parts connected to the ground electrode that are arranged in line symmetry about a median line that pass through the center of the slit and arranged perpendicular to the path,
wherein a first convex part is arranged closer to the coupling reducing electrode than another of the plurality of convex parts, and
wherein the coupling reducing electrode is connected to the ground electrode at a second of the plural of convex parts.
