  • MIMO antenna arrangement
    Patent number: 10879969
    Abstract: A device comprises antennas and a signal processor, and each antenna comprises antenna elements. The signal processor is configured to: receive an input signal for a multiple-input multiple-output (MIMO) operation; generate complex weights; generate feed signals based on the input signal and the complex weights; and provide the feed signals to the antenna elements so that the MIMO operation uses at least two antenna elements from two different antennas.
    Type: Grant
