Abstract
Embodiments of antenna systems and radio nodes incorporating the antenna systems are disclosed herein. In one embodiment, a radio access node for a cellular communications system comprises one or more antenna systems comprising a first antenna system directed at a desired bore sight angle. The one or more antenna systems further comprise either or both of a second antenna system directed upwards relative to the desired bore sight angle of the first antenna system and a second antenna system directed downwards relative to the desired bore sign angle of the first antenna system. In this manner, the radio access is optimized for an indoor environment because it can add Single User Multiple Input Multiple Output (SU-MIMO) channels by utilizing reflections from the ceiling and floor in the indoor environment.
