  • Active MIMO antenna configuration for maximizing throughput in mobile devices
    Patent number: 8928541
    Abstract: An active antenna system and algorithm is proposed that provides for dynamic tuning and optimization of antenna system parameters for a MIMO system that will provide for greater throughput. As one or multiple antennas are loaded or de-tuned due to environmental changes, corrections to correlation and/or isolation are made by tuning the active antenna. A null-steering technique is implemented to alter the near-field and far-field characteristics to aid in modifying correlation and isolation in the multi-antenna system.

  • Pre-optimization of transmit circuits
    Patent number: 8843085
    Abstract: An impedance tuning and optimization technique is described wherein an impedance interface is dynamically tuned prior to applying transmit power to the circuit. A coupled signal injected into the antenna port is used to optimize the tuning state of a tuning component such that the impedance properties of the circuit are optimized prior to application of transmit power. A coupled or injected signal at an alternate frequency band can be utilized to determine tuning state or parameters at the frequency of interest by first tuning at the frequency of the coupled or injected signal and then accessing a data base containing information that relates tuning parameters across multiple frequency bands for various levels of antenna de-tuning. A time-savings is realized when the tuning circuit is optimized prior to activation or use of the transmit/receive path.
