1. A multiple-input multiple-output (MIMO) antenna system, comprising:
- a data encoder configured to encode data to be transmitted via radio transmission;
a plurality of parallel radios coupled to the data encoder, the plurality of parallel radios configured to up-convert the data from the encoders into RF signals; and
a MIMO antenna apparatus coupled to the plurality of parallel radios, the MIMO antenna apparatus forming directional radiation patterns for transmission of the RF signals to a remote receiving node, the MIMO antenna apparatus occupying a vertical space.

Abstract
High gain, multi-pattern multiple-input multiple-output (MIMO) antenna systems are disclosed. These systems provide for multiple-polarization and omnidirectional coverage using multiple radios, which may be tuned to the same frequency. The MIMO antenna systems may include multiple high-gain beams arranged (or capable of being arranged) to provide for omnidirectional coverage. These systems provide for increased data throughput and reduced interference without sacrificing the benefits related to size and manageability of an associated access point.
