Patent ID: 7616159

Claim:
An antenna array comprising: a ground plane; a plurality of spacers, each mounted on and protruding perpendicularly from the ground plane, and having a top end and a bottom end; a radiating patch array mounted on the spacers, separated from the ground plane at a first interval and having a pair of first radiating patches, a pair of second radiating patches and a pair of third radiating patches, the first, second and third radiating patches of each pair mounted respectively on and held on the top ends of two of the spacers and separated from the ground plane, and each of the first, second and third radiating patches being parallel to the ground plane and having an inside edge; an outside edge; and a sub radiating patch being a distal portion having an outside free end, formed on and protruding transversely out from the outer edge of the first, second or third radiating patch, separated from the ground plane at the first interval and inclined away from the ground plane at an included angle between the first, second or third radiating patch and the sub radiating patch, and the included angle is in a range of 20 to 90 degrees; and a feeding member separated from the ground plane at a second interval and connected to the pairs of the first, second and third radiating patches.
