摘要
A system and method of operating an antenna in a beamforming mode or a multiple-input multiple-output (MIMO) mode. The method includes activating a first group of antenna elements to operate the antenna in the beamforming mode; and activating a second group of antenna elements to operate the antenna in the MIMO mode. The distance between adjacent antenna elements of the first group may be a half-wavelength at the antenna operating frequency, and the distance between adjacent antenna elements of the second group may be greater than a half-wavelength. If the antenna elements are configured as an array, the first group may include all of the elements of the array, and the second group may include only the elements in every other column of the array. The operation of the antenna in either the beamforming mode or the MIMO mode may be based on the RF environment in which subscriber units reside.
