  • Patent number: 9837726
    Abstract: The multi-band active integrated MIMO antenna is a planar structure that includes active devices such as power amplifiers (PA) for transmit modes, as well as low-noise-amplifiers (LNA) for receive modes or complete transceivers (both PA and LNA for bi-directional operation, i.e. transmit and receive modes simultaneously). The antenna provides active loading to facilitate a diversity advantage expected from 4G and 5G wireless systems. The integrated active amplifier device within the antenna increases system throughput while supporting multi-band operation for multi-wireless standards. Moreover, integration with the radio frequency front end eases matching while providing higher gain.
