US Patent 7646343 Multiple-input multiple-output wireless antennas

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 turned 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.
