Abstract: A microstrip antenna includes an insulating carrier, a circular body, two circular feeding points, a grounding element, and a power divider. The circular body has a first center and a radius. The two circular feeding points are surrounded by the circular body and are not connected. The two circular feeding points can produce a capacitive effect with the circular body. Each of the two circular feeding points has a second center, and a shortest distance between the second center and the first center is less than ½ of the radius. The grounding element is disposed on the insulating carrier. The power divider can generate a phase difference of 90 degrees between the two circular feeding points.
