Claim 11:
12. A method for manufacturing an antenna module, the method comprising:
defining a drill hole in a first insulating layer;
coating a metal layer on an inner surface of the drill hole and forming a connection patch connected to the metal layer and a first radiation patch including a first opening defined therein surrounding the connection patch on a top surface of the first insulating layer;
stacking a second insulating layer on the top surface of the first insulating layer;
defining a first via hole penetrating the second insulating layer and connected to the connection patch;
forming a first via by filling the first via hole with metal, and forming a second radiation patch on a top surface of the second insulating layer;
stacking a third insulating layer on the top surface of the second insulating layer;
forming a second via hole penetrating the third insulating layer and connected to the first via; and
forming a second via by filling the second via hole with metal and forming a coupling patch on a top surface of the third insulating layer.
