Abstract: The present invention discloses an antenna array installed on a printed circuit board, which comprises two antenna units, each being a microstrip directly installed on two symmetric ends of a T-shape microstrip on a printed circuit board and an asymmetric end of the T-shape microstrip circuit being a feeding end feeding signals simultaneously to the two antenna units. A grounding metal surface is fabricated on the other side of the printed circuit board at a position other than the antenna unit, and keeps a specific distance from at least one corresponding edge of the antenna unit. Since the antenna units are symmetric in shape and have the same feeding end, the radiation direction thereof is shifted towards the two symmetric edges to broaden the range of the use of two symmetric edges.
