| 摘要 |
An antenna array comprising at least two groups of antennas where each group comprises at least two pairs of antennas. Each of the pairs in a group contains orthogonally polarized antennas and at least one antenna in a pair is similarly polarized to one antenna in at least another pair in the group. The antenna array further comprises circuitry coupled to the antenna groups to select and activate certain antennas in a group to enable the antenna array to operate in either a beam forming/steering mode, a diversity mode or a MIMO mode or any combination thereof. The antennas in the groups are activated based on the characteristics of the signals being transmitted or received by the antenna array.
