PROBLEM TO BE SOLVED: To provide an antenna array where beam forming/steering, MIMO and diversify operations are performed in transmitted/received signals, without having to use additional antennas. SOLUTION: The antenna array includes at least two antenna groups and each of the groups includes at least two pairs of antennas. Each of the pairs in one group includes orthogonally polarized antennas, and one antenna in a pair is polarized, in a way similar to one antenna in at least another pair in the group. The antenna array includes a circuit connected to the antenna group, to select and activate the prescribed antenna in one group, to enable the antenna array to operate in either a beam forming/steering mode, and a diversity mode or an MIMO mode or any combination thereof.
