An array antenna includes a dielectric substrate ( 10 ) having an upper and a lower surfaces ( 101, 102 ), a first and a second radiating elements ( 11, 21 ), a first connecting portion ( 31 ) connecting the two radiating elements arranged on the upper surface of the dielectric substrate, a first and a second grounding elements ( 12, 22 ), and a second connecting portion ( 32 ) connecting the two grounding elements arranged on the lower surface of the dielectric substrate. A feeding point ( 4 ) is disposed on the first connecting portion and a grounding point ( 6 ) is disposed on the second connecting point. A coaxial cable ( 7 ) has an inner conductor ( 71 ) coupled to the feeding point and an outer conductor ( 72 ) coupled to the grounding point.
