| 1. A coupling antenna comprising:
a ground plane having a top surface;
a main radiating assembly mounted on the ground plane and having
a substrate mounted on the top surface of the ground plane and having a top surface and a side edge;
a feeding-and-coupling assembly mounted on the surface of the substrate and having
a feeding member mounted on the substrate and having a connecting end and a feeding end;
a coupling member mounted on the substrate, connected to the connecting end of the feeding member and having
a body section formed on and protruding from the connecting end of the feeding member;
a first coupling element formed on and protruding from the body section;
a second coupling element mounted on the substrate, corresponding to and separated from the first coupling element; and
a gap defined between the first and second coupling elements; and
an extension member mounted on the substrate and connected to first coupling element of the coupling member; and
a shorting member mounted on the substrate and connected to the ground plane; and
a secondary radiating assembly mounted on the substrate, connected to the coupling member of the main radiating assembly and
having
a first radiating patch mounted on the substrate and connected to the second coupling element of the coupling member and the
shorting member; and
a second radiating patch mounted on the substrate and connected to the first radiating patch and the shorting member.
