Abstract:
1. An antenna array comprising: an electrically conducting ground plane; a first electrically conducting wall including a lower edge and an upper boundary, the first wall being in electrical contact with the ground plane along its lower edge and extending away from the ground plane, wherein each region of the upper boundary of the first electrically conducting wall is disposed at a different height, measured with respect to the ground plane; a first plurality of antennas, each antenna disposed at a uniform distance relative to the upper boundary of the first wall; a second electrically conducting wall including a lower edge and an upper boundary, the second wall also being in electrical contact with the ground plane along its lower edge and extending away from the ground plane, the second electrically conducting wall being substantially parallel to the first wall, wherein each region of the upper boundary of the second electrically conducting wall is disposed at a different height, measured with respect to the ground plane; and a second plurality of antennas, each antenna disposed at a uniform distance relative to the upper boundary of the second wall, wherein the first and second electrically conducting walls are separated from each other by a separation distance.
