ANTENNA ARRAYS HAVING BAFFLE BOXES TO REDUCE MUTUAL COUPLING
First Claim
1. An antenna array comprising at least two or more radiating elements coupled to a ground plane, the two or more radiating elements including a first radiating element separated from a second radiating element by at least one wall that extends away from the ground plane between the first and second radiating elements such that the wall reduces mutual coupling between the first and second radiating elements.

Abstract
An exemplary antenna array includes at least two or more radiating elements coupled to a ground plane. The two or more radiating elements include a first radiating element separated from a second radiating element by at least one wall that extends away from the ground plane between the first and second radiating elements. The wall may be operable for reducing mutual coupling between the first and second radiating element.

- 1. An antenna array comprising at least two or more radiating elements coupled to a ground plane, the two or more radiating elements including a first radiating element separated from a second radiating element by at least one wall that extends away from the ground plane between the first and second radiating elements such that the wall reduces mutual coupling between the first and second radiating elements.
- 15. A dual polarization antenna array comprising a plurality of radiating elements forming a planar array extending in two orthogonal directions, each said radiating element is within a baffle box having side walls and a bottom coupled to a ground plane, the radiating elements being operable for receiving and/or transmitting two different polarizations, each said radiating element being fed by two probes such that each probe excites one of two orthogonal polarizations, the sidewalls extending between corresponding pairs of adjacent radiating elements, whereby the baffle boxes are operable to reduce the mutual coupling between the radiating elements.
- 18. A dual polarization antenna array comprising a plurality of radiating elements forming a planar array extending in two orthogonal directions, each said radiating element is within a baffle box having side walls and a bottom coupled to a substantially planar ground plane, the sidewalls extending between corresponding pairs of adjacent radiating elements, whereby the baffle boxes are operable to reduce the mutual coupling between the radiating elements.
