ABSTRACT:
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.
