PURPOSE: A wireless communications antenna is provided to arrange two radiating patches line abreast by miniaturizing a structure of a single patch antenna. CONSTITUTION: A wireless communications antenna(500) has a structure of a dielectric board(240) and a micro-strip line. The bottom plane of the micro-strip line is composed of a ground conductor side(250). Each side of a square slot(530) is eliminated. Two radiating patches(510) are miniaturized. An interval(d) between the two radiating patches is controlled. The beam width of electromagnetic wave radiation power distribution is controlled. A feeder line interlink the two radiating patch as T-shape. An input end of the feeder line is connected to a circuit board by soldering.
