Abstract

An antenna array includes five grounding plates, a signal transmission part, two radiation conductors, and a signal feed cable. The first and fifth grounding plates located at the same plane are substantially perpendicular with the second and fourth grounding plates respectively. The second and fourth grounding plates respectively connected to the first and fifth grounding plates extend with the same direction and have two holes or grooves. The third grounding plate connected between the second and fourth grounding plates is substantially perpendicular with the second and fourth grounding plates. The signal transmission part passing through the two holes or grooves is substantially perpendicular with the second and fourth grounding plates. The signal transmission part is connected between the two radiation conductors. The signal feed cable includes a central conductor connected to the signal transmission part and an outer conductor connected to the third grounding plate.
