Antenna module

An antenna module comprising:

• a main body having a top surface, a bottom surface, and a plurality of side surfaces, the top surface and the bottom surface being opposite to each other in a height direction;
• an antenna including an antenna electrode covering one side surface among the plurality of side surfaces;
• and
• a shield electrode covering the top surface without being in contact with the antenna electrode, wherein
• the main body includes
• a substrate having a first main surface and a second main surface,
• a plurality of electronic components mounted on the substrate and connected to the antenna,
• a first dielectric layer covering the first main surface and defining the top surface,
• a second dielectric layer covering the second main surface and defining the bottom surface,
• at least one first ground connection electrode being in form of a column extending through the first dielectric layer and connecting the substrate to the shield electrode, and
• at least one second ground connection electrode being in form of a column extending through the second dielectric layer and being for use in connecting the substrate to a ground of an external substrate, and
• the at least one second ground connection electrode is located within the shield electrode when viewed in the height direction.
